Hi all,

After merging the gfs2 tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

fs/gfs2/lops.c: In function 'gfs2_find_jhead':
fs/gfs2/lops.c:536:13: warning: 'bio_chained' may be used uninitialized in this function [-Wmaybe-uninitialized]
  536 |    if (!bio || (bio_chained && !off)) {
      |        ~~~~~^~~~~~~~~~~~~~~~~~~~~~~~

Introduced by commit

  1ee366c67176 ("gfs2: Another gfs2_find_jhead fix")

Cheers,
Stephen Rothwell

thanks. It's actually a false positive and I'm not getting this
warning, but I'll make the code more explicit.
