[Cluster-devel] [GFS2 PATCH] gfs2: fix gfs2_find_jhead that returns jhead with seq 0

[Abhi Das <adas@redhat.com>]

When the first log header in a journal happens to have a
sequence number of 0, a bug in gfs2_find_jhead() returns this
to be the jhead, instead of seeking forward and looking further
into the journal for a jhead with a higher sequence number.
