Gregory Nutt 936df1bcb5 Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep(). ... Squashed commit of the following: Change all calls to usleep() in the OS proper to calls to nxsig_usleep() sched/signal: Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable. sched/signal: Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.		2017-10-06 10:15:01 -06:00

kwork_queue.c	Work queue: In a recent change for a problem noted by Pascal Speck, it was noted (again by Pascal Speck) that the cancellation of existing work and replacement with new work must be atomic. Thanks, Pascal.	2017-08-31 07:43:47 -06:00
kwork_signal.c	Signal sent from work_signal() may interrupt the low priority worker thread that is already running. For example, the worker thread that is waiting for a semaphore could be woken up by the signal and break any synchronization assumption as a result. It also does not make any sense to send signal if it is already running and busy. This commit fixes it.	2016-11-06 08:00:12 -06:00
