The last argument of vb2_dc_get_user_pages() is of type enum dma_data_direction, but the caller, vb2_dc_get_userptr() passes a value which is the result of comparison dma_dir == DMA_FROM_DEVICE. This results in the write parameter to get_user_pages() being zero in all cases, i.e. that the caller has no intent to write there. This was broken by patch "vb2: replace 'write' by 'dma_dir'".

Several (15) drivers in media/usb/gspca use IF_ENABLED(CONFIG_INPUT) to decide if they should call input* interfaces, but those drivers do not build successfully when CONFIG_INPUT=m and the gspca drivers are builtin (=y). Making USB_GSPCA depend on INPUT || INPUT=n fixes the build dependencies and allows all of them to build cleanly.

Stopping the vb2 thread (as used by several DVB devices) can result in an 'UNBALANCED' warning such as this: vb2: counters for queue ffff880407ee9828: UNBALANCED! vb2: setup: 1 start_streaming: 1 stop_streaming: 1 vb2: wait_prepare: 249333 wait_finish: 249334 This is due to a race condition between stopping the thread and calling vb2_internal_streamoff(). While I have not been able to deduce the exact mechanism how this race condition can produce this warning, I can see that the way the stream is stopped is likely to lead to a race somewhere. This patch simplifies how this is done by first ensuring that the thread is completely stopped before cleaning up the vb2 queue. It does that by setting threadio->stop to true, followed by a call to vb2_queue_error() which will wake up the thread. The thread sees that 'stop' is true and it will exit. The call to kthread_stop() waits until the thread has exited, and only then is the queue cleaned up by calling __vb2_cleanup_fileio(). This is a much cleaner sequence and the warning has now disappeared. Reported-by:

.. after extensive statistical analysis of my G+ polling, I've come to the inescapable conclusion that internet polls are bad. Big surprise. But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38% margin, in a poll that people weren't even supposed to participate in. Who can argue with solid numbers like that? 5,796 votes from people who can't even follow the most basic directions? In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%, but with a total of 29,110 votes right now. Now, arguably, that vote spread is only about 3,200 votes, which is less than the almost six thousand votes that the "please ignore" poll got, so it could be considered noise. But hey, I asked, so I'll honor the votes.

I've noticed significant locking contention in memory reclaimer around sb_lock inside grab_super_passive(). Grab_super_passive() is called from two places: in icache/dcache shrinkers (function super_cache_scan) and from writeback (function __writeback_inodes_wb). Both are required for progress in memory allocator. Grab_super_passive() acquires sb_lock to increment sb->s_count and check sb->s_instances. It seems sb->s_umount locked for read is enough here: super-block deactivation always runs under sb->s_umount locked for write. Protecting super-block itself isn't a problem: in super_cache_scan() sb is protected by shrinker_rwsem: it cannot be freed if its slab shrinkers are still active. Inside writeback super-block comes from inode from bdi writeback list under wb->list_lock. This patch removes locking sb_lock and checks s_instances under s_umount: generic_shutdown_super() unlinks it under sb->s_umount locked for write. New variant is called trylock_super() and since it only locks semaphore, callers must call up_read(&sb->s_umount) instead of drop_super(sb) when they're done. Signed-off-by:

Convert the following where appropriate: (1) S_ISLNK(dentry->d_inode) to d_is_symlink(dentry). (2) S_ISREG(dentry->d_inode) to d_is_reg(dentry). (3) S_ISDIR(dentry->d_inode) to d_is_dir(dentry). This is actually more complicated than it appears as some calls should be converted to d_can_lookup() instead. The difference is whether the directory in question is a real dir with a ->lookup op or whether it's a fake dir with a ->d_automount op. In some circumstances, we can subsume checks for dentry->d_inode not being NULL into this, provided we the code isn't in a filesystem that expects d_inode to be NULL if the dirent really *is* negative (ie. if we're going to use d_inode() rather than d_backing_inode() to get the inode pointer). Note that the dentry type field may be set to something other than DCACHE_MISS_TYPE when d_inode is NULL in the case of unionmount, where the VFS manages the fall-through from a negative dentry to a lower layer. In such a case, the dentry type of the negative union dentry is set to the same as the type of the lower dentry. However, if you know d_inode is not NULL at the call site, then you can use the d_is_xxx() functions even in a filesystem. There is one further complication: a 0,0 chardev dentry may be labelled DCACHE_WHITEOUT_TYPE rather than DCACHE_SPECIAL_TYPE. Strictly, this was intended for special directory entry types that don't have attached inodes. The following perl+coccinelle script was used: use strict; my @callers; open($fd, 'git grep -l \'S_IS[A-Z].*->d_inode\' |') || die "Can't grep for S_ISDIR and co. callers"; @callers = <$fd>; close($fd); unless (@callers) { print "No matches\n"; exit(0); } my @cocci = ( '@@', 'expression E;', '@@', '', '- S_ISLNK(E->d_inode->i_mode)', '+ d_is_symlink(E)', '', '@@', 'expression E;', '@@', '', '- S_ISDIR(E->d_inode->i_mode)', '+ d_is_dir(E)', '', '@@', 'expression E;', '@@', '', '- S_ISREG(E->d_inode->i_mode)', '+ d_is_reg(E)' ); my $coccifile = "tmp.sp.cocci"; open($fd, ">$coccifile") || die $coccifile; print($fd "$_\n") || die $coccifile foreach (@cocci); close($fd); foreach my $file (@callers) { chomp $file; print "Processing ", $file, "\n"; system("spatch", "--sp-file", $coccifile, $file, "--in-place", "--no-show-diff") == 0 || die "spatch failed"; } [AV: overlayfs parts skipped] Signed-off-by: -

Introduce some function for getting the inode (and also the dentry) in an environment where layered/unioned filesystems are in operation. The problem is that we have places where we need *both* the union dentry and the lower source or workspace inode or dentry available, but we can only have a handle on one of them. Therefore we need to derive the handle to the other from that. The idea is to introduce an extra field in struct dentry that allows the union dentry to refer to and pin the lower dentry.

Pull ARM SoC fixes from Arnd Bergmann: "A few fixes that came in too late to make it into the first set of pull requests but would still be nice to have in -rc1.

Merge tag 'xfs-pnfs-for-linus-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs Pull xfs pnfs block layout support from Dave Chinner: "This contains the changes to XFS needed to support the PNFS block layout server that you pulled in through Bruce's NFS server tree merge. I originally thought that I'd need to merge changes into the NFS server side, but Bruce had already picked them up and so this is purely changes to the fs/xfs/ codebase. Summary: This update contains the implementation of the PNFS server export methods that enable use of XFS filesystems as a block layout target" * tag 'xfs-pnfs-for-linus-3.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dgc/linux-xfs: xfs: recall pNFS layouts on conflicting access xfs: implement pNFS export operations

Pull one more batch of power management and ACPI updates from Rafael Wysocki: "These are mostly fixes on top of the previously merged recent PM and ACPI material. First, one commit that broke the ACPI LPSS (Low-Power Subsystem) driver on a Dell box is reverted and there are two stable-candidate fixes for that driver. Another fix cleans up two recently added ACPI EC messages that look odd and the printk level of a noisy debug message in the core ACPI resources handling code is reduced. In addition to that we have two stable-candidate fixes for the s3c cpufreq driver, two cpuidle powernv driver updates related to Device Trees and a PNP subsystem cleanup that will allow us to get rid of some old ugliness going forward. Also there is a new blacklist entry for the ACPI backlight code. Specifics: - Revert a recent ACPI LPSS driver commit that prevented the touchpad driver from loading on Dell XPS13 (Jarkko Nikula). - Make the ACPI LPSS driver disable the I2C controllers and deassert SPI host controllers resets at startup on Intel BayTrail and Braswell SoCs in case they have been left in wrong states by the platform firmware which then may casuse fatal controller driver failures during resume from hibernation (Mika Westerberg). - Make two recently added ACPI EC messages look better (Scot Doyle). - Reduce the printk level of a recently added debug message related to ACPI resources that may become noisy in some cases (Rafael J Wysocki). - Add a new ACPI backlight blacklist entry for Samsung Series 9 (900X3C/900X3D/900X3E/900X4C/900X4D) laptops where the native backlight interface doesn't work while the ACPI based one does (Jens Reyer). - Make the PNP sybsystem's core code use __request_region() followed by __release_region() instead of __check_region() which then will allow us to get rid of the latter as it has no more users (Jakub Sitnicki). - Fix a build breakage and an issue with two __init functions that may be called after initialization in the s3c cpufreq driver (Arnd Bergmann). - Make the powernv cpuidle driver read target_residency values for idle states from a Device Tree (as we have the suitable DT bindings for that now) and improve the parsing of the powermgmt DT node in that driver (Preeti U Murthy)" * tag 'pm+acpi-3.20-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpuidle: powernv: Avoid endianness conversions while parsing DT cpufreq: s3c: remove last use of resume_clocks callback cpufreq: s3c: remove incorrect __init annotations ACPI / LPSS: Deassert resets for SPI host controllers on Braswell ACPI / LPSS: Always disable I2C host controllers ACPI / resources: Change pr_info() to pr_debug() for debug information ACPI / video: Disable native backlight on Samsung Series 9 laptops cpuidle: powernv: Read target_residency value of idle states from DT if available Revert "ACPI / LPSS: Remove non-existing clock control from Intel Lynxpoint I2C" ACPI / EC: Remove non-standard log emphasis PNP: Switch from __check_region() to __request_region()
