H A D | blk-settings.c | 762380ad Thu Jun 05 14:38:39 CDT 2014 Jens Axboe <axboe@fb.com> block: add notion of a chunk size for request merging
Some drivers have different limits on what size a request should optimally be, depending on the offset of the request. Similar to dividing a device into chunks. Add a setting that allows the driver to inform the block layer of such a chunk size. The block layer will then prevent merging across the chunks.
This is needed to optimally support NVMe with a non-zero stripe size.
