Timothy Lee reports: Hardware: CyberBlade/i1 on VIA Epia-800 Problem Description: When the framebuffer is set to 16 bpp, console's text colours are incorrect. For example, white becomes yellow, black becomes blue, etc. Steps to reproduce: 1. Load tridentfb 2. Use "setterm -n -depth 16" to request 16 bpp framebuffer The problem arose from the fact that each psuedo palette entry should be 32-bit in size, even under 16-bit display mode. Signed-off-by:

This change brings the semantics equivalent to 2.4 and also to what the man page says; Also optimises by avoiding unneeded lookup in uid cache, when who is same as the current->uid. sys_set/getpriority is rewritten in 2.5/2.6, perhaps while transitioning to the pid maps. It has now semantical bug, when uid is zero. Note that akpm also fixed refcount leak and locking in the new functions in changeset http://linus.bkbits.net:8080/linux-2.5/cset@1.1608.10.84 Signed-off-by: <pmeda@akamai.com> Acked-by:

This patch avoids a deadlock on rtnl_sem in smc_close() when bringing down an smc91x interface. The semaphore is already held by devinet_ioctl() and the pending work queue contains linkwatch_event() (scheduled by netif_carrier_off()) which also wants rtnl_sem hence it is unsafe to call flush_scheduled_work(). The solution is to track whether we have any pending work of our own and wait for that instead of flushing the entire queue. I also fixed a typo 'ence' -> 'Hence' and renamed smc_detect_phy to smc_phy_detect in order to follow the same pattern as the other smc_phy_* functions. Signed-off-by:

We check need_resched() _before_ disabling preemption. This opens up the following scenario: swapper: !need_resched() [IRQ context] wakes up a task marks idle task as need-resched swapper: acpi_processor_idle(); // sleeps until next irq instant 1msec latency introduced... normally default_idle() is safe because it re-checks need_resched with interrupts disabled before it truly halts the CPU. But acpi_processor_idle() doesnt seem to be doing this! Your trace clearly shows a missed preemption due to ACPI. I'm wondering why no-one has triggered this before, it's a really bad bug that should be fixed in 2.6.10. Signed-off-by:

The generic irq affinity code limits us to a single cpu target regardless of what the architecture supports. If required this should be done in the architecture specific ->set_affinity call. With this patch ppc64 is able to select all cpus affinity again. Signed-off-by:

What that patch does is making the first open _always_ assume that we need to revalidate/reread partition table and kills partition-parsing in register_disk(); instead we just have it do open/close and let the revalidation path in open do the job. Signed-off-by:

For reasons which escape me, blockdev_get_blocks() is returning -EIO if the mapping request straddles the end of the disk. This causes reads which straddle end-of-disk to return -EIO. Fix it up so that it correctly trims the returned result down to match the size of the device, for both reads and writes. If a write attempt is fully beyond end-of-device then return -EIO. We never get this far anyway, because generic_write_checks() will return -ENOSPC if all of the write lies outside a blockdev's i_size. Signed-off-by:

This recent fix isn't quite right: it is causing smaller-than-expected I/Os to be submitted when extending files, which causes AIO-based writes to oops. So just revert it - the bug was really over in blockdev_get_blocks() anyway. Signed-off-by:

I've written two document files, and packaged them as a patch. Two things caught my eye while I was writing this up: The header comments for CDROMREADRAW, CDROMREADMODE1, and CDROMREADMODE2 disagree with the actual source code. The header comments imply that a cdrom_read structure is used to pass data, but the source code actually reads a cdrom_msf structure and then overwrites it with raw data. I'm not sure if there's a bug in the header comments, in the driver source, or I misread something. The CDROM_LOCKDOOR ioctl seems to lock/unlock all doors on all drives, because it uses a global variable. Signed-off-by:

Stephen Rothwell noted a case where one CPU was sitting in userspace, one in stop_machine() waiting for everyone to enter stopmachine(). This can happen if migration occurs at exactly the wrong time with more than 2 CPUS. Say we have 4 CPUS: 1) stop_machine() on CPU 0creates stopmachine() threads for CPUS 1, 2 and 3, and yields waiting for them to migrate to their CPUs and ack. 2) stopmachine(2) gets rebalanced (probably on exec) to CPU 1. 3) stopmachine(2) calls set_cpus_allowed on CPU 1, sleeps awaiting migration thread. 4) stopmachine(1) calls set_cpus_allowed on CPU 0, moves onto CPU1 and starts spinning. Now the migration thread never runs, and we deadlock. The simplest solution is for stopmachine() to yield until they are all in place. Signed-off-by:

Here's a patch which fixes the deadlock Brad Fitzpatrick reported here: http://lkml.org/lkml/2004/11/14/98 The meat of the problem is a locking order reversal between the XFS I/O lock and the inode semaphore (i_sem). When we mix a number of threads doing both direct reads and writes, we hit an ABBA deadlock after a while because direct-io.c is taking and dropping i_sem after the XFS read path has already taken its I/O lock. This is the wrong way around from XFS's point of view, in particular its the opposite order to the XFS write path. So this patch changes the logic for direct reads in the DIO_OWN_LOCKING case (i.e. XFS-only case), but leaves things as is for the other two types of locking. Not real pretty, but fixes up the lock ordering and deadlock. Oh, I have tested direct reads and writes on ext3 and block devices as well, to ensure they still function correctly with the change (i.e. they don't regress, should be a no-op there) which covers the other locking cases in __blockdev_direct_IO.

When cont_prepare_write() is padding out the "hole" with zeroed pages it doesn't increase i_size at the same time. If writeback comes in during the execution of cont_prepare_write(), block_write_full_page() will think that these pages are outside i_size and will just clean the page without writing it. Fix that up by using generic_commit_write(), which will advance i_size for each page as it is dirtied. Signed-off-by:

raid10 performs resync by reading all blocks, comparing to look for The requires re-tasking a bio that was used to read, so that it can be re-used for write. So a number of fields need to be reset. The bi_bdev field was not being reset. However when using on a partition of a device, it gets changed by generic_make_request. This patch simply resets bi_bdev to the correct value. Signed-off-by:
