FENCE_WAIT(9)                     Device drivers infrastructure                     FENCE_WAIT(9)



NAME
       fence_wait - sleep until the fence gets signaled

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

ARGUMENTS
       fence
           [in] the fence to wait on

       intr
           [in] if true, do an interruptible wait

DESCRIPTION
       This function will return -ERESTARTSYS if interrupted by a signal, or 0 if the fence was
       signaled. Other error values may be returned on custom implementations.

       Performs a synchronous wait on this fence. It is assumed the caller directly or indirectly
       holds a reference to the fence, otherwise the fence might be freed before return,
       resulting in undefined behavior.
