[PATCH] Only honor the FIGETBSZ ioctl for regular files, directories, and symlinks
FIGETBSZ has an ioctl number of _IO(0x00,2) == 2, which can conflict with device driver ioctls. Let's avoid the potential for problems by only honoring the ioctl number for files where this ioctl is likely going to be useful: regular files, directories, and symlinks. Thanks to Johannes Stezenbach for pointing th... 14 Jun 2010 10:38

[RFC PATCH] mm: let the bdi_writeout fraction respond more quickly
Hi all, The fraction of vm cache allowed to each BDI as calculated by get_dirty_limits (mm/page-writeback.c) respond very slowly to changes in workload. Running a simple test that alternately writes 1Gb to sda then sdb, twice, shows the bdi_threshold taking approximately 15 seconds to reach a steady state value... 14 Jun 2010 10:38
[PATCH] perf lookup of ppc64 symbols
Currently symbol resolution does not work for 64-bit programs using perf. For this to work perf needs to lookup symbol names in the OPD. This patch adds this functionality. The OPD data is used to find symbol names when available. Signed-off-by: Anton Blanchard <anton(a)samba.org> Signed-off-by: Eric B Munson <... 14 Jun 2010 10:38

[PATCH net-next-2.6] net: NET_SKB_PAD should depend on L1_CACHE_BYTES
Le jeudi 10 juin 2010 à 22:20 -0700, David Miller a écrit : Eric, why don't we do that? Make NET_SKB_PAD's define L1_CACHE_BYTES. Reading the comments you added when the default value was changed to 64, this seems to even be your overall intent. :-) Of course right you are ;) Thanks ! [PATCH ne... 14 Jun 2010 09:32
