Subject: btrfs: allow idmapped tmpfile inode op
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=98b6ab5fc0988242114a4f0e02ed225685d9cc2b;p=linux.git

btrfs: allow idmapped tmpfile inode op

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