Date: Tue,  6 May 2008 12:37:04 +0000 (UTC)

 Module Name:   src
 Committed By:  ad
 Date:          Tue May  6 12:37:04 UTC 2008
 Modified Files:
        src/sys/kern: vfs_subr.c
 Log Message:
 PR kern/38141 lookup/vfs_busy acquire rwlock recursively
 getvnode: Use vfs_trybusy, not vfs_busy. If unmount is in progress we
 could deadlock, because vnode locks can be held during getnewvnode().
 dounmount() locks in the reverse order (vfs_busy -> vnode).
