Subject: KVM: Drop unused @may_block param from gfn_to_pfn_cache_invalidate_start()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=eefb85b3f0310c2f4149c50cb9b13094ed1dde25;p=linux.git

KVM: Drop unused @may_block param from gfn_to_pfn_cache_invalidate_start()

Remove gfn_to_pfn_cache_invalidate_start()'s unused @may_block parameter,
which was leftover from KVM's abandoned (for now) attempt to support guest
usage of gfn_to_pfn caches.

Fixes: a4bff3df5147 ("KVM: pfncache: remove KVM_GUEST_USES_PFN usage")
