Hi Xiaotian! I would actually prefer that the SLAB, SLOB, and SLUB changes were in separate patches to make reviewing easier.

[PATCH] introduce a default off mode for kmemleak
Hi, Kmemleak can be very useful in figuring out where a kernel leak is suspected, but I've run into issues it which makes it hard to enable by default - reports false positives, oom kills on low memory systems (512 MB). Although these can be addressed, there is still the memory footprint, and runtime overhead, ... 13 Jul 2010 17:31

[PATCH] inotify: allow users to request not to recieve events on unlinked children
An inotify watch on a directory will send events for children even if those children have been unlinked. This patch add a new inotify flag IN_EXCL_UNLINK which allows a watch to specificy they don't care about unlinked children. This should fix performance problems seen by tasks which add a watch to /tmp and then ... 13 Jul 2010 17:31

[PATCH 2/2] x86: remove c1e_mask
c1e_mask is redundant. The information about activated timer broadcast for AMD C1E is kept in the CPU feature flags.

[PATCH 1/2] x86: fix keeping track of AMD C1E
On my system with AMD Phenom II X6 I am seeing pauses at boot (usually during udev startup) which require a key press to continue. It only happens if C1E is enabled in the BIOS. It's caused by the APIC timer's inability to wake up the CPU from C1E (AMD erratum #400). Linux has a workaround for it, but it's not be... 13 Jul 2010 15:20
