From e1eb6b193df1e252c0650c3ba5faed4726cec73c Mon Sep 17 00:00:00 2001 From: Wei Liu <wei.liu2@citrix.com> Date: Wed, 18 Nov 2015 18:31:52 +0000 Subject: [PATCH] 9pfs: rename virtio-9p-xattr{,-user}.{c,h} to 9p-xattr{,-user}.{c,h} These three files are not virtio specific. Rename them to generic names. Fix comments and header inclusion in various files.
