Subject: SUNRPC: Add cond_resched() at the appropriate point in __rpc_execute()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=47dd8796a31e132f9e2b93a4f558a9f924a7388f;p=linux.git

SUNRPC: Add cond_resched() at the appropriate point in __rpc_execute()

Allow tasks that need to pre-empt rpciod/xprtiod to do so when it is
safe.
