Bug ID: 525062
Summary: BTRFS: allow to use xxhash instead of crc32c hashing
algorithm
Classification: Applications
Product: partitionmanager
Version First 26.08.0
Reported In:
Platform: unspecified
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
crc32c is the default hashing algorithm on BTRFS and is pretty fast, but not
collision resistant
xxhash is optimized for modern CPUs but with worse backwards compatibility

sha256 and blake2 could be added but with a warning that they are way slower
and not needed for a filesystem
