mke2fs: warn if enabling metadata_csum on a pre-3.18 kernel The metadata_csum feature (really, the journal checksum disk format) didn't stabilize until the 3.18 kernel, at which point the companion journal_csum feature was turned on by default if metadata_csum was enabled. Therefore, warn the user if they try to create such a filesystem on a pre-3.18 kernel. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
