SUNRPC: Mitigate cond_resched() in xprt_transmit()
[ Upstream commit 6f9f17287e78e5049931af2037b15b26d134a32a ]
The original purpose of this expensive call is to prevent a long
queue of requests from blocking other work.
The cond_resched() call is unnecessary after just a single send
operation.
For longer queues, instead of invoking the kernel scheduler, simply
release the transport send lock and return to the RPC scheduler.
