write in subject which file you changed, so instead:

[PATCH 2/5] Replace program_invocation_short_name with prog_name from command line

write for example:

[PATCH 2/5] tools/gputop: find program name from command line

and implement it yourself in some sensible way,
for example search for last '/' and take nsmae from that.

Kamil
