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

[David Howells]

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.
