Hello,
The TTY_FLIPBUF_SIZE is restricted to 2 * 512 bytes. Can this be
increased to support synchronous serial lines without affecting other
serial drivers which still stick to the TTY_FLIPBUF_SIZE limit ?
Thank you.
Regards,
Sriram

No. Check the code. struct tty_struct depends on being less than one
page (4 kb) in size, and making the flip bufs any much bigger will
break that.
