Subject: cleanup the RAID6 P/Q library
Date: Tue, 24 Mar 2026 07:40:35 +0100 [thread overview]
Message-ID: <20260324064115.3217136-1-hch@lst.de> (raw)
Hi all,
this series cleans up the RAID6 P/Q library to match the recent updates
to the RAID 5 XOR library and other CRC/crypto libraries. This includes
providing properly documented external interfaces, hiding the internals,
using static_call instead of indirect calls and turning the user space
test suite into an in-kernel kunit test which is also extended to
improve coverage.
Note that this changes registration so that non-priority algorithms are
not registered, which greatly helps with the benchmark time at boot time.
I'd like to encourage all architecture maintainers to see if they can
further optimized this by registering as few as possible algorithms when
there is a clear benefit in optimized or more unrolled implementations.
This series sits on top of the "cleanup the RAID5 XOR library v3" series.
