[Ghorai] I was testing this patch (Adrian's) and top of patch[1] from Hanumath; Looks working fine as functionality. Checking throughput in my omap platform.
[1] http://lkml.org/lkml/2010/7/9/35
But there are few comments on this patch from others, I think. And is not applying cleanly in latest codebase. Also following #define is conflicting with Hanumath's patch.
File: include/linux/mmc/host.h
#define MMC_CAP_ERASE           (1 << 10)
