tty: Convert ->dtr_rts() to take bool argument

2023-01-19T15:04:35+00:00

Convert the raise/on parameter in ->dtr_rts() to bool through the callchain. The parameter is used like bool. In USB serial, there remains a few implicit bool -> larger type conversions because some devices use u8 in their control messages. In moxa_tiocmget(), dtr variable was reused for line status which requires int so use a separate variable for status.

tty: Make ->set_termios() old ktermios const

There should be no reason to adjust old ktermios which is going to get discarded anyway. Reviewed-by: Andy Shevchenko Signed-off-by: Ilpo Järvinen Link: https://lore.kernel.org/r/20220816115739.10928-9-ilpo.jarvinen@linux.intel.com Signed-off-by: Greg Kroah-Hartman

tty: tty_io: Switch to vmalloc() fallback in case of TTY_NO_WRITE_SPLIT

2021-12-21T08:18:44+00:00

When TTY_NO_WRITE_SPLIT is set and 64 KiB chunks are used, allow vmalloc() fallback. Supply __GFP_RETRY_MAYFAIL to make kmalloc() preferable over vmalloc() since we may want a better performance. Note, both current users copy data to another buffer anyway, so the type of our allocation doesn't affect their expectations.
