[PATCH 1/2] JBD2: Allow feature checks before journal recovery
...offsets. So we need to check
the journal's feature bits before recovering the journal.
This is not possible with JBD2 at present, because the journal
superblock (where the feature bits reside) is not loaded from disk until
the journal is recovered.
This patch loads the journal superblock in
jbd2_journal_check_used_features() if it has not already been loaded,
allowing us to check the feature bits before journal recovery.

[PATCH 1/3] ext3/ext4: Factor out disk addressability check
As part of adding support for OCFS2 to mount huge volumes, we need to
check that the sector_t and page cache of the system are capable of
addressing the entire volume.
An identical check already appears in ext3 and ext4. This patch moves
the addressability check into its own function in fs/libfs.c and
modifies ext3 and ext4 to invoke it.
