[PATCH] Fix tty devfs mess
From: Christoph Hellwig <hch@lst.de> Currently the tty code abuses tty_driver.name as the prefix for the devfs names of the ttys. This is a very bad idea because it means the tty name changes depending on whether devfs is enabled or not, leading to different names in /proc/tty/ depending on whether we have devfs or not (and not whether it actually is mounted!) and a huge amount of ifdefs. The patch below adds a .devfs_name member instead, similar to the block device changes a few weeks ago.
