[PATCH 5.10 420/770] SUNRPC: change svc_get() to return the svc.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: NeilBrown <neilb@xxxxxxx>

[ Upstream commit df5e49c880ea0776806b8a9f8ab95e035272cf6f ]

It is common for 'get' functions to return the object that was 'got',
and there are a couple of places where users of svc_get() would be a
little simpler if svc_get() did that.

Make it so.
