Subject: 3.7.1-rc1: cifs client panic
Date: Tue, 25 Dec 2012 04:46:40 -0500 (EST) [thread overview]
Message-ID: <644615486.5925461.1356428800313.JavaMail.root@redhat.com> (raw)
Just a head-up, I just hit this while doing some cifs client-side
testing using 3.7.1-rc1 kernel (no specific cifs patches on the
top of the 3.7.1 release). Still trying to reproduce...
