set_cpus_allowed_ptr: don't use rq->migration_thread after unlock

[PATCH] Fix staging:iio:ring_sw: Fix incorrect test on successful read of last value, causes infinite loop
Signed-off-by: Jonathan Cameron <jic23(a)cam.ac.uk> --- This is a bad one. The test means that almost no reads of the last value ever succeed! Result is an infinite loop.

[PATCH] oom: fix the unsafe proc_oom_score()->badness() call
proc_oom_score(task) have a reference to task_struct, but that is all. If this task was already released before we take tasklist_lock - we can't use task->group_leader, it points to nowhere - it is not safe to call badness() even if this task is ->group_leader, has_intersects_mems_allowed() assumes it ... 30 Mar 2010 13:52

[patch v2] s390: potential buffer overflow

[PATCH 2/3] squashfs: gather everything block device specific into block.c
We use buffer_head structures for communicating with the decompressors, so provide a basic definition even if CONFIG_BLOCK=n (which results in a backendless - ie. useless - squashfs right now). --- fs/squashfs/Kconfig | 1 - fs/squashfs/Makefile | 5 +++-- fs/squashfs/backend.c | 48 +++++++++++++++... 30 Mar 2010 10:31
