c4697486fc232e821a33191d809d0ac3bb600027 - raid6: turn the userspace test harness into a kunit test

Mon, 18 May 2026 07:17:44 +0200

raid6: turn the userspace test harness into a kunit testPatch series "cleanup the RAID6 P/Q library", v3.This series cleans up the RAID6 P/Q library to match the recent updates tothe RAID 5 XOR library and other CRC/crypto libraries. This includesproviding properly documented external interfaces, hiding the internals,using static_call instead of indirect calls and turning the user spacetest suite into an in-kernel kunit test which is also extended to improvecoverage.Note that this changes registration so that non-priority algorithms arenot registered, which greatly helps with the benchmark time at boot time. I'd like to encourage all architecture maintainers to see if they canfurther optimized this by registering as few as possible algorithms whenthere is a clear benefit in optimized or more unrolled implementations.This patch (of 18):Currently the raid6 code can be compiled as userspace code to run the testsuite. Convert that to be a kunit case with minimal changes to avoidmutating global state so that we can drop this requirement.Note that this is not a good kunit test case yet and will need a lot morework, but that is deferred until the raid6 code is moved to it's newplace, which is easier if the userspace makefile doesn't need adjustmentsfor the new location first.Link: https://lore.kernel.org/20260518051804.462141-1-hch@lst.deLink: https://lore.kernel.org/20260518051804.462141-2-hch@lst.deSigned-off-by: Christoph Hellwig Acked-by: Ard Biesheuvel Tested-by: Ard Biesheuvel # kunit only on arm64Cc: Albert Ou Cc: Alexander Gordeev Cc: Alexandre Ghiti Cc: Arnd Bergmann Cc: "Borislav Petkov (AMD)" Cc: Catalin Marinas Cc: Chris Mason Cc: Christian Borntraeger Cc: Dan Williams Cc: David Sterba Cc: Heiko Carstens Cc: Herbert Xu Cc: "H.

00751d655ece97fe85ce9193542ee8396fe98651 - lib/bitrev: Introduce GENERIC_BITREVERSE

Wed, 06 May 2026 19:52:03 +0200

lib/bitrev: Introduce GENERIC_BITREVERSEThe generic bit reversal implementation is controlled by!HAVE_ARCH_BITREVERSE. This makes it difficult for architectures toprovide a hardware-accelerated implementation while being able tofall back to the generic version if needed.This patch adds GENERIC_BITREVERSE, so bitreverse API is controlled byBITREVERSE, GENERIC_BITREVERSE and HAVE_ARCH_BITREVERSE options. Therelationship between them is described as follows: - BITREVERSE is selected by user code; it's required to generate the API; - Architectures may select HAVE_ARCH_BITREVERSE and provide an arch implementation in arch/$(ARCH)/include/asm/bitrev.h. - if HAVE_ARCH_BITREVERSE isn't set, BITREVERSE selects GENERIC_BITREVERSE; - if GENERIC_BITREVERSE is set and HAVE_ARCH_BITREVERSE is not, the kernel provides generic implementation only, and wires bitrevXX() to it. - if HAVE_ARCH_BITREVERSE is set and GENERIC_BITREVERSE is not, the arch code provides __arch_bitrevXX(), and it is wired to bitrevXX(); - if both GENERIC_BITREVERSE and HAVE_ARCH_BITREVERSE are selected, the kernel generates generic___bitrev(), but wires bitrev() to the __arch_bitrev().The last option allows architectures to use generic___bitrev() as afallback option.Drivers and core code should never select GENERIC_BITREVERSE orHAVE_ARCH_BITREVERSE explicitly.Architectures that require generic bitreverse API as a fallback shouldexplicitly enable GENERIC_BITREVERSE together with HAVE_ARCH_BITREVERSE.Signed-off-by: Yury Norov List of files: /linux/lib/Kconfig
