When hibernate() is called again (probably after fixing up so that swsusp_write() wouldn't fail again), before "in_suspend = 1" of create_image is called, in_suspend should be 0. However, because hibernate() did not reset "in_suspend" after a failure, it's already 1. This patch fixes such inconsistency of "in_suspend" value.

The task being frozen may wake up and not see TIF_FREEZE while the freezer fails to notice the transition and believes the task is still stopped. This patch fixes the race by making freeze_task() always go through fake_signal_wake_up() for applicable tasks. The function goes through the target task's scheduler lock and thus guarantees that either the target sees TIF_FREEZE or try_to_freeze_task() sees TASK_RUNNING.

Therefore apply this only to uses of __get_cpu_var where the address of the variable is not used.

| * | | | | | | | workqueue: allow chained queueing during destructionTejun Heo2010-12-201-1/+59

Currently, such users need to explicitly flush the workqueue multiple times depending on the possible depth of such chained queueing. This patch updates the queueing path such that a work item can queue further work items on the same workqueue even when WQ_DYING is set. The flush on destruction is automatically retried until the workqueue is empty. This guarantees that the workqueue is empty on destruction while allowing chained queueing. The flush retry logic whines if it takes too many retries to drain the workqueue. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: James Bottomley <James.Bottomley@HansenPartnership.com>

However, how that the lru lock is an innermost one, we never hold it at any caller, so the lock cost can now be avoided. We already have well working lazy dcache LRU, so it should be fine to defer LRU manipulations to scan time. Signed-off-by: Nick Piggin <npiggin@kernel.dk>

Calling | clocks_calc_mult_shift(&mult, &shift, 24MHz, NSEC_PER_SEC, 60) gives | us a multiplier of 2796202666 and a shift of 26. | | Over a large counter delta, this produces an error - lets take a count | from 362976315 to 4280663372: | | (4280663372-362976315) * 2796202666 / 2^26 - (4280663372-362976315) * (1000/24) | => -38.91872422891230269990 | | Can we do better? | | (4280663372-362976315) * 2796202667 / 2^26 - (4280663372-362976315) * (1000/24) | 19.45936211449532822051 | | which is about twice as good as the 2796202666 multiplier. | | Looking at the equivalent divisions obtained, 2796202666 / 2^26 gives | 41.66666665673255920410ns per tick, whereas 2796202667 / 2^26 gives | 41.66666667163372039794ns. The actual value wanted is 1000/24 = | 41.66666666666666666666ns. Fix this by ensuring we round to nearest when calculating the multiplier.
