MFC r358798: fusefs: fix fsync for files with multiple open handles We were reusing a structure for multiple operations, but failing to reinitialize one member. The result is that a server that cares about FUSE file handle IDs would see one correct FUSE_FSYNC operation, and one with the FHID unset. PR: 244431 Reported by: Agata <chogata@gmail.com>
