Module Name:    src
Committed By:   yamt
Date:           Fri Dec 23 15:31:40 UTC 2005

Modified Files:
        src/sys/kern: vfs_subr.c
        src/sys/sys: vnode.h
        src/sys/ufs/ffs: ffs_alloc.c
        src/sys/ufs/ufs: ufs_inode.c

Log Message:
prevent in-core vnode being freed from getting new references.
otherwise, once the corresponding bit in the inode bitmap is cleared,
an unrelated inode with the same inode number can be allocated and
ufs_ihashget() picks a stale in-core vnode for it.
