From 55db890a838c7b37256241b1fc53d6344aa79cc0 Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Tue, 21 Nov 2006 17:55:45 +0100 Subject: mmc: Allow host drivers to specify max block count Many controllers have an upper limit on the number of blocks that can be transferred in one request. Allow the host drivers to specify this and make sure we avoid hitting this limit. Also change the max_sectors field to avoid confusion. This makes it map less directly to the block layer limits, but as they didn't apply directly on MMC cards anyway, this isn't a great loss.
