* tty: enable the echoing of ^C in the N_TTY disciplineJoe Peterson2008-02-06
| | | | | | | | | | | | | | | | | Turn on INTR/QUIT/SUSP echoing in the N_TTY line discipline (e.g. ctrl-C will appear as "^C" if stty echoctl is set and ctrl-C is set as INTR). Linux seems to be the only unix-like OS (recently I've verified this on Solaris, BSD, and Mac OS X) that does *not* behave this way, and I really miss this as a good visual confirmation of the interrupt of a program in the console or xterm. I remember this fondly from many Unixs I've used over the years as well. Bringing this to Linux also seems like a good way to make it yet more compliant with standard unix-like behavior.

* tpm.c: fix crash during device removalRichard MUSIL2008-02-06
| | | | | | | | | | | | | | | | | The clean up procedure now uses platform device "release" callback to handle memory clean up. For this purpose "release" function callback was added to struct tpm_vendor_specific, so hw device driver provider can get called when it is safe to remove all allocated resources. This is supposed to fix a bug in device removal, where device while in receive function (waiting on timeout) was prone to segfault, if the tpm_chip struct was unallocated before the timeout expired (in tpm_remove_hardware).

* Allow auto-destruction of loop devicesDavid Woodhouse2008-02-06
| | | | | | | | | | | | | | | | | | | | | | | | This allows a flag to be set on loop devices so that when they are closed for the last time, they'll self-destruct. In general, so that we can automatically allocate loop devices (as with losetup -f) and have them disappear when we're done with them. In particular, right now, so that we can stop relying on the hackish special-case in umount(8) which kills off loop devices which were set up by 'mount -oloop'. That means we can stop putting crap in /etc/mtab which doesn't belong there, which means it can be a symlink to /proc/mounts, which means yet another writable file on the root filesystem is eliminated and the 'stateless' folks get happier... and OLPC trac #356 can be closed.
