Patch to fix the problem

This patch fixes the problem.

Comment 2 Robert Peterson 2009-02-16 13:03:23 EST

Easy fix; I recommend we get this in asap.  I'll let management and/or
QE decide whether I should z-stream it.

Comment 3 Robert Peterson 2009-02-17 13:56:43 EST

The patch was tested on system roth-01.  It has been pushed to the
master branch of the gfs2-utils git tree and the RHEL5 branch of the
cluster.git tree for inclusion into 5.4.  Changing status to MODIFIED.

Comment 6 Jan Stodola 2009-07-24 06:28:51 EDT

No Segmentation fault on RHEL5.4 Snapshot 3, gfs2-utils-0.1.61-1.el5, arch: x86_64 in kvm. Tested with block sizes 512, 1024, 2048 and 4096.
Moving to VERIFIED.
