Subject: [PATCH] 7/4 -ac to newer rmap
Date: Wed, 13 Nov 2002 12:50:01 -0200 [thread overview]
Message-ID: <20021113145002Z80262-18062+21@imladris.surriel.com> (raw)
I guess that after a truncate() and maybe some special ext3 transactions
anonymous pages can have page->buffers set. Not quite sure about delete
from swap cache, though ... maybe the reverse of this patch should be
applied into the -rmap tree and mainline instead ?
