As proposed by Greg K-H it is more logical to keep files for the mmc_test driver under debugfs. Additionally this patch brings seq_file API for show() method. It allows to write unlimited data to the file. Example of usage: # mount -t debugfs none /sys/kernel/debug # modprobe mmc_test [ 581.395843] mmc_test mmc0:0001: Card claimed for testing. # echo 25 > /sys/kernel/debug/mmc0/mmc0\:0001/test [ 604.568542] mmc0: Starting tests of card mmc0:0001...
