cb2f84e288 Loosen up restriction a little in sched_ufree() 2015-09-07 15:28:58 -06:00
Gregory Nutt
d78d3ef4ab Logic for delayed memory garbage collection for the case of user space memory will not work as implemented for the case of the kernel build. That is because the correct context is in place in order to free the user memory when sched_kufree is called, but will not be in place later when the memory garbage collection runs. If this feature is really needed, then some more substantial redesign is required 2015-09-07 14:40:18 -06:00

2c66e0eb2a sem_tickwait(): Add a new, non-standard function to perform timed semaphore waits. It is functionally equialent to the standard sem_timedwait(), but more efficient for use in higher performance device drivers. Requested by Max Neklyudov 2015-08-01 07:31:09 -06:00
