2.6.31-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.
