File 0397-9pfs-fix-bogus-fd-check-in-local_re.patch of Package qemu-linux-user.7445
From 458af1a555baedc8b3f0534277c7b269b6b5624a Mon Sep 17 00:00:00 2001 From: Greg Kurz <groug@kaod.org> Date: Mon, 6 Mar 2017 17:34:01 +0100 Subject: [PATCH] 9pfs: fix bogus fd check in local_remove() This was spotted by Coverity as a fd leak. This is certainly true, but also local_remove() would always return without doing anything, unless the fd is zero, which is very unlikely.
