From ce128de6260f86a990ed44a697f26d0859684f28 Mon Sep 17 00:00:00 2001 From: Maxim Patlasov Date: Wed, 2 Oct 2013 21:38:54 +0400 Subject: 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.
