[PATCH 6.10 3/9] cifs: Fix missing fscache invalidation

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

 



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

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

From: David Howells <dhowells@xxxxxxxxxx>

commit a07d38afd15281c42613943a9a715c3ba07c21e6 upstream.

A network filesystem needs to implement a netfslib hook to invalidate
fscache if it's to be able to use the cache.

Fix cifs to implement the cache invalidation hook.
