Cover letter [PATCH 0/2] mmc, block: override default max_dev_sectors
From: Mateusz Nowak <[email protected]>
commit ca369d51b3e1 ("block/sd: Fix device-imposed transfer length limits") introduced max_dev_sectors as upper limit for max_hw_sectors. This caused limitation of maximum block size to default max_dev_sectors value - 127, causing performance degradation with higher block sizes.
This patchset is allowing mmc driver to override max_dev_sectors value.
