Module Name:    src
Committed By:   perseant

Modified Files:
        src/sys/ufs/lfs: lfs.h lfs_alloc.c lfs_segment.c lfs_vfsops.c
            lfs_vnops.c

Log Message:
Fixes to address the "vinvalbuf: dirty blocks" panic that can occur when
many inodes are cleaned at once.  Make sure that we write all the pages
on vnodes that are being flushed, even if we don't think there's room;
drain v_numoutput before lfs_vflush() completes.

Also, don't allow a vnode that is in the process of being cleaned to be
chosen by getnewvnode(); this avoids a segment accounting panic in the case
that a large number of inodes are fed to lfs_markv() all at once.
