Description Andre Guibert de Bruet 2001-08-23 07:50:00 UTC

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.

Fix: 

I created a patch which addresses the issue. It is available at http://siliconlandmark.com/staff/andre/smbfs.diff .
How-To-Repeat: Either compile a kernel with smbfs or load the kld. Mount an smb filesystem and unmount it.

The problem has been worked around in rev 1.15 of smbfs_vnops.c, 
which was merged onto RELENG_4 as rev 1.2.2.4.
