CVS commit: src/sys/fs/smbfs

[Antti Kantee <pooka%netbsd.org@localhost>]

Module Name:    src
Committed By:   pooka
Date:           Tue Apr  3 14:18:19 UTC 2007

Modified Files:
        src/sys/fs/smbfs: smbfs_vfsops.c

Log Message:
In sync, skip vnodes which have a null v_data pointer.  This is a
workaround for the problem analyzed more deeply in kern/30831.  In
short, the problem is keeping the vnode on the mount point vnode
list during reclaim.  If reclaim happens to sleep (as is a possibility
with smbfs due to calling vrele() and therefore possibly VOP_INACTIVE),
code going through the entire mountpoint vnode list will hit
half-reclaimed vnodes.
