No big TTY/serial patch merge for 3.6-rc1
Hi Linus, I don't really feel comfortable sending you the tty tree at the present time to have merged for 3.6-rc1. It contains some tty changes that are still causing build problems, as Stephen has pointed out over the past week. These fixes are ...

From: Min Zhang <mzhang@mvista.com> A race condition can clear tty ldisc icanon bit unintentionally which could stop n_tty from processing received characters. It can occur when tty receiver buffer was full, e.g. 4096 chars received, 8250 ...

As mentioned before in previous TTY git pull for .38, here's the big movement of the serial drivers into the drivers/tty/ subdirectory that needed to wait until after .38-rc1 was out. It merely moves the hvc drivers to drivers/tty/hvc/ and the ...

Killing the tty lock
This is a first stab at it by making the lock per tty and using tty_mutex to cover the lookup for now. We ought to move to the lookup handing back ttys with a ref but thats a further step. It seems to mostly work but not quite reliably, so coul do ...

tty_lock held during transmit wait in close: still unresolved
Short reminder/summary: Unlike the BKL, the tty_lock mechanism that replaced it does not release the lock while sleeping. This causes the tty_lock to be held for extended periods of time when uart_close() (running with tty_lock held) tries to flush ...

I seem to ahve run into a problem which people have been pointing out for years, but never gets fixed. In tty_driver.h, the low-level driver routine wait_untiL_set takes an "int" as a timeout value: 192 struct tty_operations { 193 int ...

From: Jarkko Huijts <jarkko.huijts@gmail.com> The driver does not wait until the hardware buffer (for data from the PC to the UART line) is drained when tcdrain or close is called in an application. Solution: Implement a chars_in_buffer ...

[RFC] revoke(2) and generic handling of things like remove_proc_entry()
After some digging in procfs logics for revoking further file IO after remove_proc_entry() (and figuring out what to do for debugfs - it also needs something similar), I think I've got something that has potential to become a working revoke(2) with ...
