[patch 4/7 -mm] oom: badness heuristic rewrite
This a complete rewrite of the oom killer's badness() heuristic which is used to determine which task to kill in oom conditions. The goal is to make it as simple and predictable as possible so the results are better understood and we end up killing the task which will lead to the most memory freeing while still re... 10 Feb 2010 12:15

[patch 2/7 -mm] oom: sacrifice child with highest badness score for parent
When a task is chosen for oom kill, the oom killer first attempts to sacrifice a child not sharing its parent's memory instead. Unfortunately, this often kills in a seemingly random fashion based on the ordering of the selected task's child list. Additionally, it is not guaranteed at all to free a large amount of ... 10 Feb 2010 12:15

[patch 0/7 -mm] oom killer rewrite
This patchset is a rewrite of the out of memory killer to address several issues that have been raised recently. The most notable change is a complete rewrite of the badness heuristic that determines which task is killed; the goal was to make it as simple and predictable as possible while still addressing issues t... 10 Feb 2010 12:15

[PATCH] tracing/kprobes: fix probe parsing
From: Heiko Carstens <heiko.carstens(a)de.ibm.com> Trying to add a probe like echo p:myprobe 0x10000 > /sys/kernel/debug/tracing/kprobe_events will fail since the wrong pointer is passed to strict_strtoul when trying to convert the address to an unsigned long.

[PATCH, regression] compat_ioctl: ignore RAID_VERSION ioctl
md ioctls are now handled by the md driver itself, but mdadm may call RAID_VERSION on other devices as well. Mark the command as IGNORE_IOCTL so this fails silently rather than printing an annoying message. Reported-by: "Michael S. Tsirkin" <m.s.tsirkin(a)gmail.com> Cc: "Rafael J.

m68knommu: duplicate _ramvec[vba+CPMVEC_RISCTIMER] assignment in init_IRQ()
Hi, Looking at arch/m68knommu/platform/68360/ints.c I noted two things that stood out: 1) on line 110: _ramvec[vba+CPMVEC_RISCTIMER] = inthandler; /* reserved */ and 114: _ramvec[vba+CPMVEC_RISCTIMER] = inthandler; /* timer table */ The same definitions are used, and in the first case the comme... 10 Feb 2010 09:59
