Harvey Harrison	40bc1f2dbc	lib: fix sparse shadowed variable warning ... pos is always set before being used, no need to declare a second one inside the if() block. lib/prio_heap.c:34:7: warning: symbol 'pos' shadows an earlier one lib/prio_heap.c:30:6: originally declared here Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>	16 years ago
Paul Menage	8707d8b8c0	Fix cpusets update_cpumask ... Cause writes to cpuset "cpus" file to update cpus_allowed for member tasks: - collect batches of tasks under tasklist_lock and then call set_cpus_allowed() on them outside the lock (since this can sleep). - add a simple generic priority heap type to allow efficient collection of batches of tasks to be processed without duplicating or missing any tasks in subsequent batches. - make "cpus" file update a no-op if the mask hasn't changed - fix race between update_cpumask() and sched_setaffinity() by making sched_setaffinity() post-check that it's not running on any cpus outside cpuset_cpus_allowed().
