So the gfs2-utils patch is completely broken in that it isn't using
crc32c for lh_crc. I'm looking into finding a userspace crc32c
implementation now.
I have pushed a new version of the patch to the andyp-lhv2 branch of
gfs2-utils. It includes a crc32c implementation that originated in the
kernel and was brought to user-space in btrfs-progs. It uses hardware
support if it can.
The patch also uses fiemap in gfs2_jadd to set lh_addr, as Andreas
suggested.
