[patch 1/2] dma/timb_dma: fixup error handling in td_alloc_init_desc()
The original code tried to kfree(td_desc->desc_list) when td_desc was NULL so I re-arranged it.

sched: Track and export per task [hard|soft]irq time
* Venkatesh Pallipadi <venki(a)google.com> [2010-05-24 17:11:19]: Currently, kernel does not have accounting mechanism for softirq and hardirq times at the task level. There is irq time info in kstat_cpu which is accumulated at the cpu level. Without the task level information, the non irq run time of t... 25 May 2010 05:52

[Patch 1/4] Allow arch-specific cleanup before breakpoint unregistration
Certain architectures (such as PowerPC Book III S) have a need to cleanup data-structures before the breakpoint is unregistered. This patch introduces an arch-specific hook in release_bp_slot() along with a weak definition in the form of a stub funciton.

[PATCH 4/5] superblock: add filesystem shrinker operations
From: Dave Chinner <dchinner(a)redhat.com> Now we have a per-superblock shrinker implementation, we can add a filesystem specific callout to it to allow filesystem internal caches to be shrunk by the superblock shrinker. Rather than perpetuate the multipurpose shrinker callback API (i.e. nr_to_scan == 0 meaning ... 25 May 2010 05:52

[PATCH 0/5] Per superblock shrinkers V2
This series reworks the filesystem shrinkers. We currently have a set of issues with the current filesystem shrinkers: 1. There is an dependency between dentry and inode cache shrinking that is only implicitly defined by the order of shrinker registration. 2. The shrinkers... 25 May 2010 05:52

GFS2: Pre-pull patch posting (fixes)
Hi, These are three important, but relatively small, bug fixes for GFS2. The first prevents a kernel BUG triggering in a relatively unlikely (but possible) scenario when a log flush caused by glock demotion races with a log flush from some other initiator (e.g. fsync). The second and third patches add extra co... 25 May 2010 05:51
