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.
Cheers,
Andy
