2022-01-07	fscache, cachefiles: Store the volume coherency data	David Howells	1	-2/+23
	Store the volume coherency data in an xattr and check it when we rebind the volume. If it doesn't match the cache volume is moved to the graveyard and rebuilt anew. Changes ======= ver #4: - Remove a couple of debugging prints.

2022-01-07	cachefiles: Implement volume support	David Howells	1	-0/+118
	Implement support for creating the directory layout for a volume on disk and setting up and withdrawing volume caching. Each volume has a directory named for the volume key under the root of the cache (prefixed with an 'I' to indicate to cachefilesd that it's an index) and then creates a bunch of hash bucket subdirectories under that (named as '@' plus a hex number) in which cookie files will be created.
