Subject: [PATCH 26/27] afs: Show more a bit more server state in /proc/net/afs/servers
Date: Fri, 29 May 2020 23:03:11 +0100 [thread overview]
Message-ID: <159078979153.679399.348340971164597777.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <159078959973.679399.15496997680826127470.stgit@warthog.procyon.org.uk>
Display more information about the state of a server record, including the
flags, rtt and break counter plus the probe state for each server in
/proc/net/afs/servers.
Rearrange the server flags a bit to make them easier to read at a glance in
the proc file.
