This is the result of a git-rebase gone wrong on my side. The entire first
patch gets reverted as part of the second patch, which is not what I indented.

Sorry about the confusion. Please just apply patch 1/7 again on top of the series
to fix it up, or fold that patch into this one (block: push down BKL into
.locked_ioctl) to make it not change i2o_block.c any more.
