From fe2140e2f57fef8562e0f9b7cd447d2b08dc2f35 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 21 Oct 2021 09:55:21 +0100 Subject: cachefiles: Implement volume support 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.
