[PATCH 1/2] FS-Cache: Initialise stores_lock in netfs cookie

From: David Howells
Date: Wed Jan 18 2017 - 09:29:30 EST


Initialise the stores_lock in fscache netfs cookies. Technically, it
shouldn't be necessary, since the netfs cookie is an index and stores no
data, but initialising it anyway adds insignificant overhead.
