| From | Peter Hurley <> | Subject | [PATCH v3 09/23] tty: Remove unnecessary buffer work flush | Date | Tue, 5 Feb 2013 15:20:24 -0500 |
| |
In order to safely call tty_ldisc_flush_works(), the ldisc must already have been halted, so any pending buffer work has already been cancelled or flushed as part of the halt.
