H A D | vfs_mount.c | diff 123075 Sun Nov 30 21:30:09 MST 2003 iedowse In dounmount(), only call checkdirs() prior to VFS_UNMOUNT() in the forced unmount case. Otherwise, a file system that is referenced only by process fd_cdir/fd_rdir references to the file system root vnode will be successfully unmounted without the MNT_FORCE flag. The previous behaviour was not compatible with the unmount semantics required by amd(8), so file systems could be unexpectedly unmounted while there were still references to the file system root directory.
