Re: [PATCH 08/16] ext4: Calculate and verify checksums for inode bitmaps

[Andi Kleen]

One very interesting optimization would be to profile the metadata workload
where you got the slowdown and try to figure out which fields
were most commonly updated.

If it's some superblock fields or similar maybe those could get their separate
crcs that could be separatedly computed at much lower cost.
