Subject: [PATCH] xfs_repair: support bigtime timestamp checking
Make sure that inodes don't have the bigtime flag set when the feature
is disabled, and don't check for overflows in the nanoseconds when
bigtime is enabled because that is no longer possible. Also make sure
that quotas don't have bigtime set erroneously.
