   4 LU-8364 ext4: fixes for failover mode.
   5
   6 When ext4 runs in failover mode with read-only disk,
   7 it may loose part of allocation updates and fail while
   8 mounting fs due to group descriptor checks before journal
   9 replay not being valid after journal replay is complete.
  10 Don't produce panics with on disk checks in read-only mode.
