Subject[20/34] ext4: make "norecovery" an alias for "noload"
2.6.32-stable review patch.  If anyone has any objections, please let us know.

------------------

(cherry picked from commit e3bb52ae2bb9573e84c17b8e3560378d13a5c798)

Users on the linux-ext4 list recently complained about differences
across filesystems w.r.t. how to mount without a journal replay.

In the discussion it was noted that xfs's "norecovery" option is
perhaps more descriptively accurate than "noload," so let's make
that an alias for ext4.

Also show this status in /proc/mounts
