Comment 14 for bug 30335

I am expecting the mmc-block module to get slurped up as a dependancy on any interface specific module which is loaded. Looking at my laptop I seem to have an MMC slot so I am able to test it.

    $ lsmod | grep mmc
    mmc_core 67296 1 sdhci
    ricoh_mmc 12672 0
    $

Shoved in an SD card:

    [289098.924301] mmc0: new SD card at address e624
    [289099.085615] mmcblk0: mmc0:e624 SD01G 992000KiB
    [289099.086534] mmcblk0: p1

and now:

    $ lsmod | grep mmc
    mmc_block 19720 2
    mmc_core 67296 2 mmc_block,sdhci
    ricoh_mmc 12672 0
    $

As it was loaded on detection of the media I assume this was loaded by udev? Do you have an example where it does not work this way?
