CVS commit: syssrc/sys/kern

Module Name:    syssrc

Modified Files:
        syssrc/sys/kern: vfs_subr.c

Log Message:
In getnewvnode(), allocate a vnode from the pool with NOWAIT.  If
that fails, just try to recycle a vnode.  If we can't allocate or
recycle, issue a warning, sleep a bit, and try the whole thing
again.

This prevents us from blocking forever if we want to use a very large
number of vnodes, but don't have {memory,kva} resources from which to
allocate them.
