If a daemon never responds to FUSE_INIT, but some process attempts to access the mountpoint, and a different process (possibly the daemon itself) attempts to unmount, a deadlock would result. Fix this bug by blocking any thread that enters fuse_vfsop_root until the daemon responds to FUSE_INIT or it times out. That will block any thread attempting to lookup a path in the fuse mountpoint, before it even gets to fuse VOPs. Remove less thorough initialization checks in fuse_ticket_fetch and fuse_vnop_access that are no longer necessary. And add a test case.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
