Subject: [PATCH 22/24] afs: Add fs_context support [ver #7]
Date: Thu, 19 Apr 2018 14:33:42 +0100	[thread overview]
Message-ID: <152414482204.23902.6333006978830726557.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <152414466005.23902.12967974041384198114.stgit@warthog.procyon.org.uk>

Add fs_context support to the AFS filesystem, converting the parameter
parsing to store options there.

This will form the basis for namespace propagation over mountpoints within
the AFS model, thereby allowing AFS to be used in containers more easily.
