Matthew D Fleming e7ceb1e99b Based on discussions on the svn-src mailing list, rework r218195: ... - entirely eliminate some calls to uio_yeild() as being unnecessary, such as in a sysctl handler. - move should_yield() and maybe_yield() to kern_synch.c and move the prototypes from sys/uio.h to sys/proc.h - add a slightly more generic kern_yield() that can replace the functionality of uio_yield(). - replace source uses of uio_yield() with the functional equivalent, or in some cases do not change the thread priority when switching. - fix a logic inversion bug in vlrureclaim(), pointed out by bde@. - instead of using the per-cpu last switched ticks, use a per thread variable for should_yield(). With PREEMPTION, the only reasonable use of this is to determine if a lock has been held a long time and relinquish it. Without PREEMPTION, this is essentially the same as the per-cpu variable.		2011-02-08 00:16:36 +00:00
