Pull up following revision(s) (requested by bouyer in ticket #1129):
sys/kern/vfs_subr.c: revision 1.386
sys/ufs/ufs/ufs_ihash.c: revision 1.28
getcleanvnode(): don't vclean() the vnode if it has gained another
reference while we were getting the v_interlock.
vget(): attempt prevent it from returning a clean vnode:
if the vnode is being inactivated (by vrelel()), wait for
vrelel() to complete (or return EBUSY if we can't wait), and return
ENOENT if the vnode has been vclean'ed by vrelel()
Fix kern/41147 in a better way, hopefully fix other related race conditions.
