Ok. This repo is merged.

I had to add a small build fix. Can you verify it's correctness ?

Are you sure the -H (hex) flag is used ? gcc reports the flag as unused.
If it's not used I think you should either remove it from the usage
message and man or add the feature.

On the same topic:
in mpathpersist,
main.c:403:7: attention : variable ‘t_arr_len’ set but not used
[-Wunused-but-set-variable]

and in libmpathpersist,
mpath_persist.c: In function ‘mpath_send_prin_activepath’:
mpath_persist.c:397:20: attention : variable ‘param’ set but not used
[-Wunused-but-set-variable]
mpath_persist.c: In function ‘mpath_prout_common’:
mpath_persist.c:553:15: attention : variable ‘pptemp’ set but not used
[-Wunused-but-set-variable]
mpath_pr_ioctl.c: In function ‘dumpHex’:
mpath_pr_ioctl.c:519:15: attention : variable ‘formatstr’ set but not
used [-Wunused-but-set-variable]


Also I though sg_persist has IN mode set as default, so that simple
commands are simple to write : sg_persist -r /dev/sda. Can we restore
that nice feature ?

Anyway, thanks for the great work.
