[PATCH] BLOCK: Move extern declarations out of fs/*.c into header files [try #6]

2006-09-30T18:52:18+00:00

Create a new header file, fs/internal.h, for common definitions local to the
sources in the fs/ directory.

Move extern definitions that should be in header files from fs/*.c to
fs/internal.h or other main header files where they span directories.

[PATCH] Fix tty layer DoS and comment relevant code

2006-08-27T18:01:34+00:00

Unlike the other tty comment patch this one has code changes.  Specifically
it limits the queue size for a tty to 64K characters (128Kbytes) worst case
even if the tty is ignoring tty->throttle.  This is because certain drivers
don't honour the throttle value correctly, although it is a useful
safeguard anyway.

[PATCH] tty: Remove include of screen_info.h from tty.h

2006-07-10T20:24:16+00:00

screen_info.h doesn't have anything to do with the tty layer and shouldn't be
included by tty.h.  This patches removes the include and modifies all users to
directly include screen_info.h.  struct screen_info is mainly used to
communicate with the console drivers in drivers/video/console.  Note that this
patch touches every arch and I have no way of testing it.  If there is a
mistake the worst thing that will happen is a compile error.

[PATCH] vt: Remove VT-specific declarations and definitions from tty.h

2006-07-10T20:24:16+00:00

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one.  Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

[PATCH] remove active field from tty buffer structure

2006-06-28T21:59:05+00:00

Remove 'active' field from tty buffer structure.  This was added in 2.6.16
as part of a patch to make the new tty buffering SMP safe.  This field is
unnecessary with the more intelligently written flush_to_ldisc that adds
receive_room handling.

Removing this field reverts to simpler logic where the tail buffer is
always the 'active' buffer, which should not be freed by flush_to_ldisc.
(active == buffer being filled with new data)

The result is simpler, smaller, and faster tty buffer code.

[PATCH] remove TTY_DONT_FLIP

2006-06-28T21:59:05+00:00

Remove TTY_DONT_FLIP tty flag.  This flag was introduced in 2.1.X kernels
to prevent the N_TTY line discipline functions read_chan() and
n_tty_receive_buf() from running at the same time.  2.2.15 introduced
tty->read_lock to protect access to the N_TTY read buffer, which is the
only state requiring protection between these two functions.

The current TTY_DONT_FLIP implementation is broken for SMP, and is not
universally honored by drivers that send data directly to the line
discipline receive_buf function.

Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is
not universally honored, it is removed.

[PATCH] TTY: return class device pointer from tty_register_device()

2006-06-21T19:40:47+00:00

Let tty_register_device() return a pointer to the class device it creates.
This allows registrants to add their own sysfs files under the class
device node.
