2009-09-19cyclades: remove block_til_readyJiri Slaby
Use a tty_port common instead. This saves lots of .text and makes the code a lot more readable. This involves separation of a dtr_rts handling, next patches will use that to not duplicate the code all over the place.

2009-09-19cyclades: add tty refcountingJiri Slaby
While this is not problem for Y card handlers (they are protected by card_lock), Z handlers and other functions may dereference NULL at any point after hangup/close. Even if (tty == NULL) was already performed in the handler. Note that it's not an issue for Y cards just for now. After switching to tty_port_close_* et al. this will be a problem. So add refcounting to them all. Also proc .show doesn't take a tty reference and it should (along with a ldisc one). While at it and changing prototypes (adding tty param), prepend cy_ to functions which don't have it yet.

2009-09-19tty-ldisc: get rid of tty_ldisc_try_get() helper functionLinus Torvalds
Now that the /proc/tty/ldiscs handling doesn't play games with 'struct ldisc' any more, the only remaining user of 'tty_ldisc_try_get()' is 'tty_ldisc_get()' (note the lack of 'try'). And we're actually much better off folding the logic directly into that file, since the 'try' part was always about trying to get the ldisc operations, not the ldisc itself: and making that explicit inside of 'tty_ldisc_get()' clarifies the whole semantics.

2009-09-19tty-ldisc: make /proc/tty/ldiscs use ldisc_ops instead of ldiscsLinus Torvalds
The /proc/tty/ldiscs file is totally and utterly un-interested in the "struct tty_ldisc" structures, and only cares about the underlying ldisc operations. So don't make it create a dummy 'struct ldisc' only to get a pointer to the operations, and then destroy it. Instead, we split up the function 'tty_ldisc_try_get()', and create a 'get_ldops()' helper that just looks up the ldisc operations based on the ldisc number. That makes the code simpler to read (smaller and more well-defined helper functions), and allows the /proc functions to avoid creating that useless dummy only to immediately free it again.

This allows subsytems to provide devtmpfs with non-default permissions for the device node. Instead of the default mode of 0600, null, zero, random, urandom, full, tty, ptmx now have a mode of 0666, which allows non-privileged processes to access standard device nodes in case no other userspace process applies the expected permissions.

2009-09-19perf: Add the timechart toolArjan van de Ven
timechart is a tool to visualize what is going on in the system. The user makes a trace of what is going on with > perf record --timechart /usr/bin/some_command and then can turn the output of this into an svg file > perf timechart which then can be viewed with any SVG view; inkscape works well enough for me.
