SubjectRe: [PATCH 1/2] mm/compaction: correct comment of candidate pfn in fast_isolate_freepages
From
Date
Hi Baolin, I try to resend a new v2 patchset, the patch 1 is still
missing. Here is the patch 1 in old version and I find it in lore
archive of lore.kernel.org with link [1].
It's likely that patch 1 is denied by linux-mm.kvack.org but accepted
by linux-kernel@vger.kernel.org. Is anyone know how to submit issue of
linux-mm.kvack.org, please let know. Thanks!
