Subject: Avoid closing se->fd twice in fuse_lowlevel.c (#516)
X-Git-Tag: fuse-3.9.2~2
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9126a7b48e2c27fb0ce19785181286b15a438f76;p=qemu-gpiodev%2Flibfuse.git

Avoid closing se->fd twice in fuse_lowlevel.c (#516)

If fuse_session_unmount is called before fuse_session_destroy, both
would try to close(se->fd). Avoid that by resetting it in
fuse_session_unmount.
