This patch adds xattr support to tmpfs, and a security xattr handler. The purpose of this is to allow udev to be mounted on tmpfs, as used currently by Fedora. Original patch from: Luke Kenneth Casson Leighton <lkcl@lkcl.net>. Signed-off-by:

This patch replaces the dentry parameter with an inode in the LSM inode_{set|get|list}security hooks, in keeping with the ext2/ext3 code. dentries are not needed here. Signed-off-by: -

This patch consolidates common xattr handling logic into the core fs code, with modifications suggested by Christoph Hellwig (hang off superblock, remove locking, use generic code as methods), for use by ext2, ext3 and devpts, as well as upcoming tmpfs xattr code. Signed-off-by:

The last change to alloc_layer in lib/idr.c unnecessarily complicates the code and depending on the definition of spin_unlock will cause worse code to be generated than necessary. The following patch should improve the situation. Signed-off-by:

This patch fixes "Samba Bugzilla Bug 999". The last version (2.6.8.1) of smbfs kernel module do not honor uid, gid, file_mode and dir_mode supplied by user during mount. This bug is also logged as "Kernel Bug Tracker Bug 3330". To fully work, some modifications are needed to samba smbmount.c and smbmnt.c files. Those patches are available at Samba and Kernel Bug Tracker pages. After those patches, if the user do not supply any of the parameters above, the uid, gid, file_mode and dir_mode on the server will be used by the client. Signed-off-by:

This patch adds machine check tainting. When a handled machine check occurs the oops gets a new 'M' flag. This is useful to ignore machines with hardware problems in oops reports. On i386 a thermal failure also sets this flag. Done for x86-64 and i386 so far. Signed-off-by:

Finally some in-tree documentation for RCU-based dcache look-up. Signed-off-by:

Tested using dcachebench and hevy rename test. http://lse.sourceforge.net/locking/dcache/rename_test/ While going over dcache code, I realized that d_bucket which was introduced to prevent hash chain traversals from going into an infinite loop earlier, is no longer necessary. Originally, when RCU based lock-free lookup was first introduced, dcache hash chains used list_head. Hash chain traversal was terminated when dentry->next reaches the list_head in the hash bucket. However, if renames happen during a lock-free lookup, a dentry may move to different bucket and subsequent hash chain traversal from there onwards may not see the list_head in the original bucket at all. In fact, this would result in the list_head in the bucket interpreted as a list_head in dentry and bad things will happen after that. Once hlist based hash chains were introduced in dcache, the termination condition changed and lock-free traversal would be safe with NULL pointer based termination of hlists. This means that d_bucket check is no longer required. There still exist some theoritical livelocks like a dentry getting continuously moving and lock-free look-up never terminating. But that isn't really any worse that what we have. In return for these changes, we reduce the dentry size by the size of a pointer. That should make akpm and mpm happy. Signed-off-by:

__d_lookup() has leftover stuff from earlier code to protect it against rename. The smp_rmb() there was needed for the sequence counter logic. Original dcache_rcu had : + move_count = dentry->d_move_count; + smp_rmb(); + if (dentry->d_name.hash != hash) continue; if (dentry->d_parent != parent) continue; This was to make sure that comparisons didn't happen before before the sequence counter was snapshotted. This logic is now gone and memory barrier is not needed. Removing this should also improve performance. The other change is the leftover smp_read_barrier_depends(), later converted to rcu_dereference(). Originally, the name comparison was not protected against d_move() and there could have been a mismatch of allocation size of the name string and dentry->d_name.len. This was avoided by making the qstr update in dentry atomic using a d_qstr pointer. Now, we do ->d_compare() or memcmp() with the d_lock held and it is safe against d_move(). So, there is no need to rcu_dereference() anything. In fact, the current code is meaningless. Signed-off-by: -

This patch moves some definitions among time.h, times.h, timex.h and jiffies.h. The purpose is to sort all jiffies related functions to jiffies.h, to get rid of the cyclic dependency between time.h & timex.h and to move all #include lines to the start of the header files. Signed-off-by:

For non-smp kernels the call to update_process_times is done in the do_timer function. It is more consistent with smp kernels to move this call to the architecture file which calls do_timer. Signed-off-by:

These had been officially deprecated since Rusty's module rewrite, but never got the __deprecated marker. The only remaining users are drm and mtd, so we'll get some warnings for common builds. But maybe that's the only way to get the drm people to fix the mess :) Signed-off-by:

Relatively minor add-on (not necessarily tied to it or required to be taken or a fix for any bug). Since cond_resched() is using PREEMPT_ACTIVE now, it may be useful to update the open-coded instance of cond_resched() to use the generic call. Also, it should probably be __sched so the caller shows up in wchan. Signed-off-by:

In arch/i386/kernel/acpi/boot.c, platform GSI does not propagate back from mp_register_gsi() to a calling routine which results in IRQ to be set for wrong GSI. This causes most of the PCI slots on the first PCI module to fail. This patch fixes the problem by returning new GSI back to acpi_register_gsi(). Signed-off-by:

Having recently repaired autofs' ability to recognise updates to maps dynamically I found I needed to reintroduce the directory inode lookup method (I broke the update recognition several versions ago, oops). This patch does this and applies cleanly against 2.6.9-rc1-mm4. As far as I can tell from testing it doesn't introduce any backward incompatibilities. Signed-off-by:

The pid_max sysctl doesn't enforce PID_MAX_LIMIT or sane lower bounds. RESERVED_PIDS + 1 is the minimum pid_max that won't break alloc_pidmap(), and PID_MAX_LIMIT may not be aligned to 8*PAGE_SIZE boundaries for unusual values of PAGE_SIZE, so this also rounds up PID_MAX_LIMIT to it. Signed-off-by:

For several months I'm receiving complaints from matroxfb users that v4lctl suddenly stops working for them on kernel upgrade. Problem is that VIDIOC_S_CTRL was renumbered, but all distros still use old VIDIOC_S_CTRL value (f.e. even xawtv-3.94 in Debian unstable still uses old VIDIOC_S_CTRL definition). So let's add this old VIDIOC_S_CTRL value (now named VIDIOC_S_CTRL_OLD) to matroxfb's v4l handling. Signed-off-by:

This patch cleans up some old cruft in the manipulation of the LVDS interface registers and fixes the blanking code to work with various DVI flat panels. Since this is all very sensitive stuff, I'm posting the patch here for testing before submitting it upstream, though Andrew is welcome to put it in -mm. It also fix some problems with getting the right PLL setup on recent Mac laptops, replacing the old hard coded list of values with cleaner code that "probes" the PLL setup done by the firmware.

This small change does: (1) Properly document 'outputs' option. (2) Properly use accelerated characters drawing. fbcon used depth == 0 for character painting long ago, but it is fixed for several months. (3) Provide correct hints for fbcon about matroxfb/matroxfb_crtc2 hardware capabilities. Signed-off-by: -

One of the PowerPC developers, Kostas Georgiou, pointed out to me discussion back from 2001 that they would prefer little endian mode as majority of users runs XF4.x and not Xpmac. And apparently nobody runs Xpmac now, so we can safely remove big-endian mode from matroxfb completely. So let's simplify matroxfb a bit: Accelerator and ILOAD fifo is now always in little endian mode. This is what XFree does. Due to this change all #ifdefs based on endianness was removed from driver - except one which selects framebuffer endinaness (but there is no code in matroxfb which writes to framebuffer directly). It seems that while I was not looking m68k got ioremap, and all architectures now offer ioremap and ioremap_nocache. Let's kill code which mapped ioremap_nocache to ioremap, and ioremap to bus_to_virt for architectures which did not provide them. And this also fixes small typo - M_C2CTL should be 0x3C10 and not 0x3E10. Apparently Matrox notes about need to program this register during initialization are not so important... Signed-off-by:
