| H A D | tty_outq.c | diff 182471 Sat Aug 30 07:18:47 MDT 2008 ed Fix some edge cases in the TTY queues: - In the current design, when a TTY decreases its baud rate, it tries to shrink the queues. This may not always be possible, because it will not free any blocks that are still filled with data. Change the TTY queues to store a `quota' value as well, which means it will not free any blocks when changing the baud rate, but when placing blocks back into the queue. When the amount of blocks exceeds the quota, they get freed. It also fixes some edge cases, where TIOCSETA during read()/ write()-calls could actually make the queue a tiny bit bigger than in normal cases. - Don't leak blocks of memory when calling TIOCSETA when the device driver abandons the TTY while allocating memory. - Create ttyoutq_init() and ttyinq_init() to initialize the queues, instead of initializing them by hand. The new TTY snoop driver also creates an outq, so it's good to have a proper interface to do this. Obtained from: //depot/projects/mpsafetty/... |
