FreeBSD theta.properkernel.com 4.4-RC FreeBSD 4.4-RC #0: Thu Aug 23 00:26:18 EDT 2001     root@theta.properkernel.com:/usr/src/sys/compile/THETA  i386
>Description:
Unmounting an smbfs filesystem generates a "Negative opencount" message on two (so far) different 4.4-RC i386 machines. I have been able to reproduce this with both the kld and the in-kernel versions of smbfs. I traced down the error message and it comes from a call to smb_closel() in /usr/src/sys/fs/smbfs/smbfs_vnops.c.
>How-To-Repeat:
Either compile a kernel with smbfs or load the kld. Mount an smb filesystem and unmount it.
>Fix:
I created a patch which addresses the issue. It is available at http://siliconlandmark.com/staff/andre/smbfs.diff .
