[PATCH] scsi/st: remove BKL from open
The st_open function is serialized through the st_dev_arr_lock and the STp->in_use flag, so there is no race that the BKL can protect against in the driver itself, and the function does not access any global state outside of the driver that might be protected with the BKL.

[PATCH 6/6] usb/mon: kill BKL usage
compat_ioctl does not use the BKL, so I assume that the native function does not need it either. The open function is already protected by the driver's mutex, the BKL is probably not needed here either.

[PATCH 0/6] USB: BKL removal
Hi Greg, Here goes another series of BKL removal patches, mostly from Andi. There are some minor drivers left in the USB subsystem that someone should take care of, but this series at least gets to the point where USB works with the BKL disabled. Please apply to your USB next tree. Arnd Andi Kleen (4):... 1 Jun 2010 17:31

[PATCH 2/6] USB-BKL: Convert usb_driver ioctl to unlocked_ioctl
From: Andi Kleen <ak(a)linux.intel.com> And audit all the users. None needed the BKL. That was easy because there was only very few around.

[PATCH 5/6] usb/gadget: Do not take BKL for gadget->ops->ioctl
There is no gadget driver in the tree that actually implements the ioctl operation, so obviously it is not necessary to hold the BKL around the call.

[PATCH 1/6] USB-BKL: Remove lock_kernel in usbfs update_sb()
From: Andi Kleen <ak(a)linux.intel.com> The code this is attempting to lock against does not use the BKL, so it's not needed. Most likely this code is still broken/racy (Al Viro also thinks so), but removing the BKL should not make it worse than before.

[PATCH 01/31] stallion: prune lock_kernel calls
From: Alan Cox <alan(a)linux.intel.com> Remove unneeded tty layer lock kernel bits. Relock the needed bits using the port mutex. The istallion still has brd state races but those are not new or introduced by the removal of the lock_kernel logic.

[PATCH 29/31] tty: implement BTM as mutex instead of BKL
The tty locking now follows the rules for mutexes, so we can replace the BKL usage with a new subsystem wide mutex. This patch for now makes the new behaviour an optional experimental feature that can be enabled for testing purposes. Using a regular mutex here will change the behaviour when blocked on the BT... 1 Jun 2010 17:31
