As per http://www.nist.gov/dads/HTML/shellsort.html, this should be referred to as a Shell sort. Shell-Metzner is a misnomer. Signed-off-by:

The regression test in lib/sort.c is currently worthless because the array that is generated for sorting will be all zeros. This patch fixes things so that the array that is generated will contain unsorted integers (that are not all identical) as was probably intended.

When I do a "diff -Nur arch/i386 arch/x86_64" to see what is different between these two architectures, I see some differences due to whitespace issues only. The attached patch removes some of the noise by fixing up the following files: - arch/i386/boot/bootsect.S - arch/i386/boot/video.S - arch/x86_64/boot/bootsect.S Signed-off-by:

Attached is a patch to bttv which fixes the following problems. Affected cards and problems: ~~~~~~~~~~~~~~~~~~~~~~~~ o VP-1020 (200103A) Tuning problems, device detection. o VP-1020 (DST-MOT) Errors during tuning, device detection fails in a while. o VP-1030 (DST-CI) Tuning sometimes fails after CI commands. o VP-2031 (DCT-CI) Tuning problems The timeout happens before the actual timeout occured in the MCU on the board, and hence the problems. Changes: (bttv-i2c.diff) ~~~~~~~~~~~~~~~~~~~~~~~~ o Changed the custom wait queue to wait_event_interruptible_timeout() - Suggestion by Johannes Stezenbach. o Fixed the wait queue timeout problem - This fixes the timeout problem on various cards. - This problem was visible as many * Cannot tune to channels, when signal levels are very low. * app_info does not work in some conditions for CI based cards - Smaller values worked good for newer cards, but the older cards suffered, settled down to the worst case values that could happen in any eventuality.

This patch adds support for a new class of DAC960 controllers. It's based on the GPLed idac320 driver from IBM for Linux 2.4.18. That driver is a fork of the 2.4.18 version of DAC960 that adds support for this new type of controllers (internally called "GEM Series"), that differ from other DAC960 V2 firmware controllers only in the register offsets and removes support for all others. This patch instead integrates support for these controllers into the DAC960 driver. Thanks to Anders Norrbring for pointing me to the idac320 driver and testing this patch. No Signed-Off: line because all code is either copy & pasted from IBM's idac320 driver or support for other controllers in the 2.6 DAC960 driver. Note: the really odd formating matches the rest of the DAC960 driver. Cc: Dave Olien <dmo@osdl.org> Signed-off-by:

It seems that the code responsible for this is in kernel/itimer.c:126: p->signal->real_timer.expires = jiffies + interval; add_timer(&p->signal->real_timer); If you request an interval of, lets say 900 usecs, the interval given by timeval_to_jiffies will be 1. If you request this when we are half-way between two timer ticks, the interval will only give 400 usecs. If we want to guarantee that we never ever give intervals less than requested, the simple solution would be to change that to: p->signal->real_timer.expires = jiffies + interval + 1; This however will produce pathological cases, like having a idle system being requested 1 ms timeouts will give systematically 2 ms timeouts, whereas currently it simply gives a few usecs less than 1 ms. The complex (and more computationally expensive) solution would be to check the gettimeofday time, and compute the correct number of jiffies. This way, if we request a 300 usecs timer 200 usecs inside the timer tick, we can wait just one tick, but not if we are 800 usecs inside the tick. This would also mean that we would have to lock preemption during these computations to avoid races, etc. I've searched the archives but couldn't find this particular issue being discussed before. Attached is a patch to do the simple solution, in case anybody thinks that it should be used. Signed-Off-By:

The `last_bh' logic probably isn't worth much. In those situations where only the front part of the page is being written out we will save some looping but in the vastly more common case of an all-page writeout if just adds more code. Nick Piggin <nickpiggin@yahoo.com.au> Signed-off-by:

Remove all those get_bh()'s and put_bh()'s by extending lock_page() to cover the troublesome regions. (get_bh() and put_bh() happen every time whereas contention on a page's lock in there happens basically never). Cc: Nick Piggin <nickpiggin@yahoo.com.au> Signed-off-by:

When running fsstress -v -d $DIR/tmp -n 1000 -p 1000 -l 2 on an ext2 filesystem with 1024 byte block size, on SMP i386 with 4096 byte page size over loopback to an image file on a tmpfs filesystem, I would very quickly hit BUG_ON(!buffer_async_write(bh)); in fs/buffer.c:end_buffer_async_write It seems that more than one request would be submitted for a given bh at a time. What would happen is the following: 2 threads doing __mpage_writepages on the same page. Thread 1 - lock the page first, and enter __block_write_full_page. Thread 1 - (eg.) mark_buffer_async_write on the first 2 buffers. Thread 1 - set page writeback, unlock page. Thread 2 - lock page, wait on page writeback Thread 1 - submit_bh on the first 2 buffers. => both requests complete, none of the page buffers are async_write, end_page_writeback is called. Thread 2 - wakes up. enters __block_write_full_page. Thread 2 - mark_buffer_async_write on (eg.) the last buffer Thread 1 - finds the last buffer has async_write set, submit_bh on that. Thread 2 - submit_bh on the last buffer. => oops. So change __block_write_full_page to explicitly keep track of the last bh we need to issue, so we don't touch anything after issuing the last request. Signed-off-by:

Fix a race where __block_prepare_write can leak out an in-flight read against a bh if get_block returns an error. This can lead to the page becoming unlocked while the buffer is locked and the read still in flight. __mpage_writepage BUGs on this condition. BUG sighted on a 2-way Itanium2 system with 16K PAGE_SIZE running fsstress -v -d $DIR/tmp -n 1000 -p 1000 -l 2 where $DIR is a new ext2 filesystem with 4K blocks that is quite small (causing get_block to fail often with -ENOSPC).
