Subject: xen-blkfront: remove IRQF_SAMPLE_RANDOM which is now a no-op
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89c30f161cd03d9baa4c88105b0449ce7025d713;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

xen-blkfront: remove IRQF_SAMPLE_RANDOM which is now a no-op

With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a
no-op; interrupt randomness is now collected unconditionally in a very
low-overhead fashion; see commit 775f4b297b.  The IRQF_SAMPLE_RANDOM
flag was scheduled to be removed in 2009 on the
feature-removal-schedule, so this patch is preparation for the final
removal of this flag.
