Subject2.5.35-mm1

url: http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.35/2.5.35-mm1/

Significant rework of the new sleep/wakeup code - make it look totally
different from the current APIs to avoid confusion, and to make it
simpler to use.

Also increase the number of places where this API is used in networking;
Alexey says that some of these may be negative improvements, but
performance testing will nevertheless be interesting. The relevant
patches are:

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.35/2.5.35-mm1/broken-out/prepare_to_wait.patch
http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.35/2.5.35-mm1/broken-out/tcp-wakeups.patch

A 4x performance regression in heavy dbench testing has been fixed. The
VM was accidentally being fair to the dbench instances in page reclaim.
It's better to be unfair so just a few instances can get ahead and submit
more contiguous IO. It's a silly thing, but it's what I meant to do anyway.

Since 2.5.34-mm4:

-readv-writev.patch
-aio-sync-iocb.patch
-llzpr.patch
-buffermem.patch
-lpp.patch
-lpp-update.patch
-reversemaps-leak.patch
-sharedmem.patch
-ext3-sb.patch
-pagevec_lru_add.patch
-oom-fix.patch
-tlb-cleanup.patch
-dump-stack.patch
-wli-cleanup.patch

Merged

+release_pages-speedup.patch

Avoid a couple of lock-takings.

-wake-speedup.patch
+prepare_to_wait.patch

Renamed, reworked

+swapoff-deadlock.patch
+dirty-and-uptodate.patch
+shmem_rename.patch
+dirent-size.patch
+tmpfs-trivia.patch
