[PATCH] Kconfig: Make config Filter access to /dev/mem default y
Recently, most company start use >=2.6.31 kernels to replace redhat kernels. But the config "Filter access to /dev/mem" is "default n", that allows kernel rootkit using /dev/mem again. it could access all kernel memory default. Most administrator don't known the "Filter access to /dev/mem" is "defult N", when he c... 12 Apr 2010 23:40

Linux 2.6.34-rc4
It's been two weeks rather than the usual one, because we've been hunting a really annoying VM regression that not a lot of people seem to have seen, but I didn't want to release an -rc4 with it. So we had the choice of either reverting all the anon-vma scalability improvements, or finding out exactly what ca... 14 Apr 2010 17:48

[PATCH] mm: disallow direct reclaim page writeback
From: Dave Chinner <dchinner(a)redhat.com> When we enter direct reclaim we may have used an arbitrary amount of stack space, and hence enterring the filesystem to do writeback can then lead to stack overruns. This problem was recently encountered x86_64 systems with 8k stacks running XFS with simple storage configu... 12 Apr 2010 22:34

[PATCH 0/2] Context sensitive memory shrinker support
Recently I made the XFS inode reclaim operate entirely in the background for both clean and dirty inodes as it simplified the code a lot and is somewhat more efficient. Unfortunately, there are some workloads where the background reclaim is not freeing memory fast enough, so the reclaim needs an extra push when mem... 12 Apr 2010 22:33

[RFC PATCH 1/2] hw-breakpoints: Separate constraint space for data and instruction breakpoints
There are two outstanding fashions for archs to implement hardware breakpoints. The first is to separate breakpoint address pattern definition space between data and instruction breakpoints. We then have typically distinct instruction address breakpoint registers and data address breakpoint registers, delivered ... 12 Apr 2010 20:21
