[LU-1025] Lustre crc32c implementation not use final bit inversion

• Type: Improvement
• Resolution: Fixed
• Priority: Blocker
• Fix Version/s: Lustre 2.2.0
• Affects Version/s: Lustre 2.2.0
• Assignee: Andreas Dilger

Description

LU-241 add crc32c crypto hash algorithm to ost(osc) checksum. But this implementation differ from base crc32c at linux kernel(intel implementation on crc32 instruction and table crc32c implementation) at final bit inversion.
