[PATCH] fix loop driver for large BIOs
Fix the loop driver for loop-on-blockdev setups.
When presented with a multipage BIO, loop_make_request overindexes the
first page and corrupts kernel memory. Fix it to walk the individual
pages.
BTW, I suspect the IV handling in loop may be incorrect for multipage
BIOs. Should we not be recalculating the IV for each page in the BIOs,
or incrementing the offset by the size of the preceding pages, or such?
