Re: [PATCH 16/16] tty: drop tty_flip_buffer_push

Friendly ping Johan, Greg: any opinions on the tty_schedule_flip vs tty_flip_buffer_push case -- which one should I keep?

I would like to move forward with these as I have a lot kernel-doc writings pending and depending on this patch (be it "drop tty_flip_buffer_push" or "drop tty_schedule_flip").

Thanks.

Since commit a9c3f68f3cd8d (tty: Fix low_latency BUG) in 2014,

Did you consider inlining tty_flip_buffer_push() or unexporting
tty_schedule_flip() instead?

Yes -- I see no reason for two functions doing the very same thing. It's only confusing.

The name tty_flip_buffer_push() is arguable more descriptive since the
work may already be running and is also less tied to the implementation.

The ratio of drivers using tty_flip_buffer_push() over
tty_schedule_flip() is also something like 186 to 15 so that would
amount to a lot less churn too.

OK, I can do either way. I chose this path as tty_schedule_flip was a wrapper to tty_flip_buffer_push. In any case, I wouldn't take the number of changed drivers as a measure. But if it makes more sense for people regarding the naming, I will "flip" the two flips.
