Modified Files: src/sys/kern: vfs_syscalls.c Log Message: Fix reference counting for vfsops in mount. Otherwise it's possible (for an unprivileged user) to force vfs modules to remain loaded forever. Also, it's possible for an admin with fat fingers to have to curse out loud (a lot) and reboot. .. or at least fix things as much as seems to be possible without involving 1000 zorkmids. do_sys_mount() takes either struct vfsops (which hopefully came properly referenced) or a userspace string for file system type. The standard in-kernel calling convention of "do_sys_mount(l, vfs_getopsbyname("nfs"), NULL," is not to be considered healthy, kosher, or even tasty (although if vfs_getopsbyname() fails the whole thing *currently* fails without the program counter pointing to hyperspace).
