Subject: btrfs: allow idmapped symlink inode op
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5a0521086e5fc5eb51690d4fc63fd26fdb5ae881;p=linux.git

btrfs: allow idmapped symlink inode op

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