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. Signed-off-by: Maxim Patlasov <MPatlasov@parallels.com> Signed-off-by: Miklos Szeredi <mszeredi@suse.cz>
