Message-ID: <20131002110254.26932.38934.stgit@dhcp-10-30-17-2.sw.ru> Date: Wed, 02 Oct 2013 15:03:19 +0400 From: Maxim Patlasov <MPatlasov@...allels.com> To: miklos@...redi.hu Cc: fuse-devel@...ts.sourceforge.net, linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 5/5] fuse: writepages: protect secondary requests from fuse file release All async fuse requests must be supplied with extra reference to a fuse file. This is necessary to ensure that the fuse file is not released until all in-flight requests are completed. Fuse secondary writeback requests must obey this rule as well.
