Subject: [Qemu-devel] [PATCH v2 1/3] block/gluster: rename [server, volname, image] -> [host, volume, path]
Date: Tue, 10 Nov 2015 14:39:14 +0530 [thread overview]
Message-ID: <1447146556-7328-2-git-send-email-prasanna.kalever@redhat.com> (raw)
In-Reply-To: <1447146556-7328-1-git-send-email-prasanna.kalever@redhat.com>
this patch is very much be meaningful after next patch which adds multiple
gluster servers support. After that,
an example is, in 'servers' tuple values we use 'server' variable for key
'host' in the code, it will be quite messy to have colliding names for
variables, so to maintain better readability and makes it consistent with other
existing code as well as the input keys/options, this patch renames the
following variables
'server' -> 'host'
'image' -> 'path'
'volname' -> 'volume'
