Subject: btrfs: allow idmapped getattr inode op
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c020d2eaf1a84ba8611fe2a232f4951faa98e0e0;p=linux.git

btrfs: allow idmapped getattr inode op

Enable btrfs_getattr() to handle idmapped mounts. This is just a matter
of passing down the mount's userns.
