This adds a single file, "unbind", to the sysfs directory of every device that is currently bound to a driver. To unbind the driver from the device, write anything to this file and they will be disconnected from each other. Signed-off-by:Greg Kroah-Hartman <gregkh@suse.de>

get_request is now expected to be holding on to queue_lock, with interrupts disabled, when it returns NULL; but one path forgot that, causing all kinds of nastiness under swap load - badness backtraces, strange failures, BUGs. Signed-off-by:

* bttv-driver.c, bttvp.h: - New bttv module params: - uv_ratio : allow a ratio of saturation between u and v. If you have a ratio of 40 and a saturation of 100, usat will be 80 and vstat 120. Useful to correct a bad color balance. - full_luma_range : provide a better contrast in using the full range 0-253 of values instead of 16-253. - coring : to have a better black level. - radio range is now defined on tuner-core.c.

Anyone reporting a stuck IRQ should try these options. Its effectiveness varies we've found in the Fedora case. Quite a few systems with misdescribed IRQ routing just work when you use irqpoll. It also fixes up the VIA systems although thats now fixed with the VIA quirk (which we could just make default as its what Redmond OS does but Linus didn't like it historically). A small number of systems have jammed IRQ sources or misdescribes that cause an IRQ that we have no handler registered anywhere for. In those cases it doesn't help. Signed-off-by:

Currently in ext3 block reservation code, the global filesystem reservation tree lock (rsv_block) is hold during the process of searching for a space to make a new reservation window, including while scaning the block bitmap to verify if the avalible window has a free block. Holding the lock during bitmap scan is unnecessary and could possibly cause scalability issue and latency issues. This patch tries to address this by dropping the lock before scan the bitmap. Before that we need to reserve the open window in case someone else is targetting at the same window. Question was should we reserve the whole free reservable space or just the window size we need. Reserve the whole free reservable space will possibly force other threads which intended to do block allocation nearby move to another block group(cause bad layout). In this patch, we just reserve the desired size before drop the lock and scan the block bitmap. This patch fixed a ext3 reservation latency issue seen on a cvs check out test. Patch is tested with many fsx, tiobench, dbench and untar a kernel test. Signed-Off-By:

get_io_context needlessly turned off interrupts and checked for racing io context creations. Both of which aren't needed, because the io context can only be created while in process context of the current process. Also, split the function in 2. A light version, current_io_context does not elevate the reference count specifically, but can be used when in process context, because the process holds a reference itself. Signed-off-by:

In the case where the request is not able to be merged by the elevator, don't retake the lock and retry the merge mechanism after allocating a new request. Instead assume that the chance of a merge remains slim, and now that we've done most of the work allocating a request we may as well just go with it. Also be rid of the GFP_ATOMIC allocation: we've got working mempools for the block layer now, so let's save atomic memory for things like networking. Lastly, in get_request_wait, do an initial get_request call before going into the waitqueue. This is reported to help efficiency. Signed-off-by:

We add a check of the return value of tty_ldisc_ref(), which is checked 7 out of 8 times, e.g.: 149 ld = tty_ldisc_ref(tty); 150 if (ld != NULL) { 151 if (ld->set_termios) 152 (ld->set_termios)(tty, &old_termios); 153 tty_ldisc_deref(ld); 154 } This defect was found automatically by Coverity Prevent, a static analysis tool.

This patch cleans up asm-ppc64/byteorder.h to enable ___arch__swab16 and ___arch__swab32 which are marked TODO currently. It removes ___arch__swab64 because ppc64 does not have short instruction combinations for swab64, the recent gcc generates enough smart code that is equivalent to hand assembled code under my tests.

In the case of buffered AIO, in the aio retry path (aio_run_iocb), when the retry method returns EIOCBRETRY the kicked iocb is added to the context run list but is never queued onto the work queue. The request therefore is never completed. This patch fixes that by adding the appropriate call to aio_queue_work in aio_run_aiocb so that subsequent retries will be handled by the aio worker thread.

As Steven Rostedt pointed out, there are 2 problems with ITIMER_REAL timers. 1. do_setitimer() does not call del_timer_sync() in case when the timer is not pending (it_real_value() returns 0). This is wrong, the timer may still be running, and it can rearm itself. 2. It calls del_timer_sync() with tsk->sighand->siglock held. This is deadlockable, because timer's handler needs this lock too. Signed-off-by:
