While these symbols are no longer available to modules in 2.6.25-rc4, it
seems suspicious that blkback is the only user of them (outside of the
block/ directory) even in 2.6.18 (and starting with 2.6.17, where all the
other blk_put_queue() users were converted to blk_cleanup_queue(),
which isn't what blkback wants; there were no other users of
blk_get_queue() even in 2.6.5 - didn't check older code). Would it be
possible for someone familiar with the block layer and blkback's
interface to it to determine whether these calls aren't really left-overs?

Thanks, Jan
