Subject: [PATCH 0/2] mmc, block: override default max_dev_sectors
Date: Wed, 2 Mar 2016 09:54:15 +0100 [thread overview]
Message-ID: <cover.1456847028.git.pawelx.wodkowski@intel.com> (raw)
From: Mateusz Nowak <mateusz.nowak@intel.com>
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.

Mateusz Nowak (2):
block: Allow to set max_dev_sectors for a queue.
mmc/block: Override default max_dev_sectors.
