Subject: [PATCH v2 52/67] cachefiles: Allow cachefiles to actually function
Date: Thu, 09 Dec 2021 17:06:04 +0000	[thread overview]
Message-ID: <163906956491.143852.4951522864793559189.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <163906878733.143852.5604115678965006622.stgit@warthog.procyon.org.uk>

Remove the block that allowed cachefiles to be compiled but prevented it
from actually starting a cache.
