Although it's trivial, we need descritpion.
Please, could you resend to Andrew Morton with filling description?

I don't know... do we want to have it as a separate patch?
may be we can fold it into some other patch someday later.

Xishi spent his time to make the patch(review,create/send). And I want to
give a credit to him. :)

sure, I didn't mean "let's seize the credit" :)  my reasoning was
that that patch hardly can be counted even as trivial. per
documentation:

: Trivial patches must qualify for one of the following rules:
:
: - Spelling fixes in documentation
: - Spelling fixes for errors which could break :manpage:`grep(1)`
: - Warning fixes (cluttering with useless warnings is bad)
: - Compilation fixes (only if they are actually correct)
: - Runtime fixes (only if they actually fix things)
: - Removing use of deprecated functions/macros
: - Contact detail and documentation fixes
: - Non-portable code replaced by portable code (even in arch-specific,
:   since people copy, as long as it's trivial)
: - Any fix by the author/maintainer of the file (ie. patch monkey
:   in re-transmission mode)


hence was my question. we can have it as "p.s. in this patch we also
remove XYZ reported by Xishi Qiu".

but up to you.



for instance, we can have Xishi's fix up as part of this "fix documentation
typos" patch. which can be counted in as trivial.

Xishi, Could you send your patch with fixing ones Sergey pointed out
if Sergey doesn't mind?

You should include Sergey's SOB, too.

Hmm, discontinuous is right?
I'm not a native but discontiguos is wrong? "contiguous" was used mm part widely.

oh, you're definitely much closer to native speaker than `aspell' tool!
you're right. Xishi, please drop that 'discontiguous' "correction".
sorry for that.

Hi, Minchan and Sergey,

OK, but I will have a vacation soon, so could you just add
that typo in your patch? or I will resend v3 several days later.

works for me. the patch is trivial, so I definitely can wait for v3.
if there is a chance to find additional trivial corrections/tweaks
then I wouldn't mind to include them into v3 as well. I just want
to keep the trivial patch flow at min level.

have a good vacation.
