Mark Johnston 465659643b Augment wait queue support in the LinuxKPI. ... In particular: - Don't evaluate event conditions with a sleepqueue lock held, since such code may attempt to acquire arbitrary locks. - Fix the return value for wait_event_interruptible() in the case that the wait is interrupted by a signal. - Implement wait_on_bit_timeout() and wait_on_atomic_t(). - Implement some functions used to test for pending signals. - Implement a number of wait_event_*() variants and unify the existing implementations. - Unify the mechanism used by wait_event_*() and schedule() to put the calling thread to sleep. This is required to support updated DRM drivers. Thanks to hselasky for finding and fixing a number of bugs in the original revision.
