[PATCH v2 0/6] dm verity: optionally use tasklets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Please see this updated patchset that reflects what I've staged for
the 5.20 merge window, see:
https://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm.git/log/?h=dm-5.20

My only outstanding question, from previous v1 patchset, is: should
the verify_wq be created using WQ_HIGHPRI instead of WQ_CPU_INTENSIVE?
(I doubt it has a significant impact on performance but if you have
insight on why you made that change, and if it meaningful, I'd happily
apply the change).

I've tested using cryptsetup's testsuite (which has dm-verity tests)
but I haven't tested the "try_verify_in_tasklet" feature.

I'd welcome review and focused "try_verify_in_tasklet" testing.

Thanks,
Mike
