Thomas Gleixner c1e16aa279 [PATCH] Fix posix-cpu-timer breakage caused by stale p->last_ran value ... Problem description at: http://bugzilla.kernel.org/show_bug.cgi?id=8048 Commit b18ec80396 [PATCH] sched: improve migration accuracy optimized the scheduler time calculations, but broke posix-cpu-timers. The problem is that the p->last_ran value is not updated after a context switch. So a subsequent call to current_sched_time() calculates with a stale p->last_ran value, i.e. accounts the full time, which the task was scheduled away.
