From 1e6be9c19c1286cdc3e87a27b06038361a0165ab Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Wed, 22 Feb 2017 20:08:25 +0100 Subject: fuse: add missing FR_FORCE commit 2e38bea99a80eab408adee27f873a188d57b76cb upstream. fuse_file_put() was missing the "force" flag for the RELEASE request when sending synchronously (fuseblk). If this flag is not set, then a sync request may be interrupted before it is dequeued by the userspace filesystem. In this case the OPEN won't be balanced with a RELEASE.
