patch -- Amit's patch ported to 5.1 beta kernels
Same patch as Amit's patch but fixed up to apply to 5.1 beta kernels.
For QA purposes, could you elaborate on exactly how you reproduce this issue? i.e. how are you running locktest here? Was able to reproduce this pretty quickly by running the ltp locktest like this: # locktest -n 50 -f /file/on/cifs ...while running "service smb restart" in a loop on the server. I want to reproduce it a couple of times to make sure I can do it reliably and then I'll test whether the patch fixes it. in 2.6.18-42.el5 You can download this test kernel from http://people.redhat.com/dzickus/el5 reproduced problem using testcase in comment 11 using the -40 kernel, was unable to reproduce it using the -45 kernel. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2007-0959.html |
