Re: [PATCH tty-next 14/22] tty: Remove tty_wait_until_sent_from_close()

On Mon, Jun 16, 2014 at 09:17:11AM -0400, Peter Hurley wrote:

tty_wait_until_sent_from_close() drops the tty lock while waiting
for the tty driver to finish sending previously accepted data (ie.,
data remaining in its write buffer and transmit fifo).

However, dropping the tty lock is a hold-over from when the tty
lock was system-wide; ie., one lock for all ttys.

Since commit 89c8d91e31f267703e365593f6bfebb9f6d2ad01,
'tty: localise the lock', dropping the tty lock has not been necessary.

I've applied the first 13 patches in this series, as it looks like you
were going to split things up from here, right?  Can you refresh these
and resend when you have that done?

thanks,
