Dammit, there's a reason I don't use this abomination:

$ cat /tmp/0001-x86-resctrl-Remove-redundant-variable-in-mbm_config_.patch | ./scripts/checkpatch.pl

WARNING: Prefer a maximum 75 chars per line (possible unwrapped commit description?)
#9:
commit 54e35eb8611c ("x86/resctrl: Read supported bandwidth sources from CPUID").


WTF?!

I have a line underneath which is even one char longer:

" commit 92bd5a139033 ("x86/resctrl: Add interface to write mbm_total_bytes_config")"

but it doesn't complain about it.

What a bunch of crap.

I'm writing it as a maximally readable commit message and that's it.
Human-readable beats any script, any day of the week.

Thx.
