[Juergen Hannken-Illjes <hannken%netbsd.org@localhost>]

Module Name:    src
Committed By:   hannken
Date:           Mon Jun 12 16:37:00 UTC 2006

Modified Files:
        src/sys/ufs/ffs: ffs_softdep.c

Log Message:
softdep_sync_metadata: If vp is a block device it may have new I/O requests
posted for it even if the vnode is locked. This will deadlock with wmesg
"softgetdbuf" if it gets a BMSAFEMAP dependency as here we have "bp == nbp"
and try to get a buffer we already own.
