4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Theodore Ts'o <[email protected]> commit 4753d8a24d4588657bc0a4cd66d4e282dff15c8c upstream. If the file system requires journal recovery, and the device is read-ony, return EROFS to the mount system call. This allows xfstests generic/050 to pass.
