FENCE_WAIT_TIMEOUT(9)             Device drivers infrastructure             FENCE_WAIT_TIMEOUT(9)



NAME
       fence_wait_timeout - sleep until the fence gets signaled or until timeout elapses

SYNOPSIS
       signed long fence_wait_timeout(struct fence * fence, bool intr, signed long timeout);

ARGUMENTS
       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

DESCRIPTION
       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.
