	    lfs_segment.c lfs_subr.c lfs_syscalls.c lfs_vfsops.c

Log Message:
Changes to stabilize LFS.  The first two of these should also apply to the
1.4 branch.

* Use a separate per-fs lock, instead of ufs_hashlock, to protect the Inode
  free list.  This seems to prevent the "lockmgr: %d, not exclusive lock holder
  %d, unlocking" message I was mis-attributing last night to an unlocked vnode
  being passed to vrele.

* Change calling semantics of lfs_ifind, to give better error reporting:
  If fed a struct buf, it can report the block number of the offending inode
  block as well as the inode number.

* Back out rev 1.10 of lfs_subr.c, since the replacement code was slightly
  uglier while being functionally identical.

* Make lfs_vunref use the same free list convention as vrele/vput, so that
  vget does not remove vnodes from a hash list they are not on.
