[PATCH 0/7] block: BKL removal, version 4

[Arnd Bergmann <arnd@arndb.de>]

This series removes the big kernel lock from the common
block layer code by pushing it into the individual
device drivers.

This version incorporates further changes to address
comments from Christoph Hellwig and Sam Ravnborg,
many thanks for the valuable feedback!

I'd like to get this into 2.6.36 in order to remove
the BKL from all the core kernel code.

Once Christoph is happy with the series, in particular
the third patch, I'd like to add it to linux-next
for broader testing, preferrably though Jens Axboe's
linux-2.6-block.git tree.

Arnd Bergmann (7):
  scsi/i2o_block: cleanup ioctl handling
  block: push down BKL into .locked_ioctl
  block: push down BKL into .open and .release
  block: push BKL into blktrace ioctls
  block: remove BKL from BLKROSET and BLKFLSBUF
  block: remove BKL from partition ioctls
  scsi/sd: remove big kernel lock
