Gregory Nutt 83cdb0c552 Squashed commit of the following: ... libc/semaphore: Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable. Changed all references to sem_getvalue in the OS to nxsem_getvalue(). sched/semaphore: Rename all internal private functions from sem_xyz to nxsem_xyz. The sem_ prefix is (will be) reserved only for the application semaphore interfaces. libc/semaphore: Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable. Changed all references to sem_init in the OS to nxsem_init(). sched/semaphore: Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function. sched/semaphoate: Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.		2017-10-03 12:52:31 -06:00

sem_trywait.c	sem_wait() and sem_trywait() no longer modify the errno value UNLESS an error occurs. This allows these functions to be used internallly without clobbering the errno value.	2016-11-09 07:01:49 -06:00

spinlock.c	SMP: There were certain conditions that we must avoid by preventing releasing the pending tasks while withn a critical section. But this logic was incomplete; there was no logic to prevent other CPUs from adding new, running tasks while on CPU is in a critical section.	2016-12-27 08:49:07 -06:00
