Description:
The iofunc_unblock() function unblocks any clients that are blocked on any internal resource manager structures.
Currently, this involves only the advisory lock list that's maintained by the attribute.
If a client connection is found:
- that client is unblocked, and is replied to with the error EINTR.
- iofunc_unblock() returns _RESMGR_NOREPLY.
If no client connection is found, iofunc_unblock() returns _RESMGR_DEFAULT.
Returns:
- _RESMGR_DEFAULT
- No client connection was found.
- _RESMGR_NOREPLY
- A client connection has been unblocked.
