fence_wait_timeout — sleep until the fence gets signaled or until timeout elapses
signed long fence_wait_timeout ( | struct fence * fence, |
| bool intr, | |
signed long timeout); |
fence[in] the fence to wait on
intr[in] if true, do an interruptible wait
timeout[in] timeout value in jiffies, or MAX_SCHEDULE_TIMEOUT
Returns -ERESTARTSYS if interrupted, 0 if the wait timed out, or the remaining timeout in jiffies on success. Other error values may be returned on custom implementations.
Performs a synchronous wait on this fence. It is assumed the caller directly or indirectly (buf-mgr between reservation and committing) holds a reference to the fence, otherwise the fence might be freed before return, resulting in undefined behavior.
