Random assortment of refactoring and trivial cleanups; Previous posting: http://thread.gmane.org/gmane.linux.kernel.bcache.devel/1055 No big changes since v2 - incorporated review feedback - mostly documentation, did more testing, and fixed the deadlock Vivek noticed in my "convert integrity to bvec_alloc_bs()" patch. Patch series is on top of my patches for fixing a bio allocation deadlock with stacked blocked devices, which is on top of Jens' tree. Git tree is at: http://evilpiepirate.org/git/linux-bcache.git block_stuff v2: Patch series now has all the prep work to be done before abstracting out the bio iterator, I think.
