Damien Le Moal 615d22a51c block: Fix __blkdev_issue_zeroout loop ... The BIO issuing loop in __blkdev_issue_zeroout() is allocating BIOs with a maximum number of bvec (pages) equal to min(nr_sects, (sector_t)BIO_MAX_PAGES) This works since the requested number of bvecs will always be limited to the absolute maximum number supported (BIO_MAX_PAGES), but this is ineficient as too many bvec entries may be requested due to the different units being used in the min() operation (number of sectors vs number of pages). To fix this, introduce the helper __blkdev_sectors_to_bio_pages() to correctly calculate the number of bvecs for zeroout BIOs as the issuing loop progresses. The calculation is done using consistent units and makes sure that the number of pages return is at least 1 (for cases where the number of sectors is less that the number of sectors in a page). Also remove a trailing space after the bit shift in the internal loop min() call.
