Subject: btrfs: btrfs_root_readonly() broken on big-endian
From: Al Viro <[email protected]>
commit 6ed3cf2cdfce4c9f1d73171bd3f27d9cb77b734e upstream.
->root_flags is __le64 and all accesses to it go through the helpers
that do proper conversions. Except for btrfs_root_readonly(), which
checks bit 0 as in host-endian...
