        I find a bug about mmc/core/core.c, and send you a patch which I fix
this bug.

        In fact, the bug is a low probability of occurrence.

        Hope you help me to analyze it and discuss with me.

I've added the proper people - Chris Ball and linux-mmc - to the
participants list.

I also wanted to check with you: the commit message implies that this
can cause an IO timeout and then a call to
msmsdcc_start_command_deferred() with a NULL cmd->mrq. Which I assume
results in a NULL pointer dereference and Oops, but that wasn't
spelled out.

Chris, please give it a look, and perhaps edit the commit message a bit.
