Subject: [PATCH 0/2] Make PageWriteback use the PageLocked optimisation
Date: Thu, 26 Mar 2020 05:24:27 -0700 [thread overview]
Message-ID: <20200326122429.20710-1-willy@infradead.org> (raw)
From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
PageWaiters is used by PageWriteback and PageLocked (and no other page
flags), so it makes sense to use the same codepaths that have already been
optimised for PageLocked, even if there's probably no real performance
benefit to be had.
Matthew Wilcox (Oracle) (2):
mm: Remove definition of clear_bit_unlock_is_negative_byte
mm: Use clear_bit_unlock_is_negative_byte for PageWriteback
