The execution flow looks like this:
* The mmc-queue calls issue_rw_rq(), which sends the request
to the host and returns back to the mmc-queue.
* The mmc-queue calls issue_rw_rq() again with a new request.
* This new request is prepared in issue_rw_rq(), then it waits for
the active request to complete before pushing it to the host.
* When the mmc-queue is empty it will call issue_rw_rq() with a NULL
req to finish off the active request without starting a new request.

Some host controllers will not operate without a hardware

require large timeouts, so there needs to be a way to
specify the maximum discard size.
A host controller driver may now specify the maximum discard
timeout possible so that max_discard_sectors can be calculated.
However, for eMMC when the High Capacity Erase Group Size
is not in use, the timeout calculation depends on clock
rate which may change. For that case Preferred Erase Size

mmc: block: improve error recovery from command channel errors
Command channel errors fall into four classes:
1. The command was issued with the card in the wrong state
2. The command failed to be received by the card correctly
3. The cards response failed to be received by the host (CRC error)
4. The card failed to respond to the card
For (1), in theory we should know that the card is in the correct state.
However, a failed stop command (or other failure) may result in the card
remaining in a data transfer state from the previous command. If we
detect this condition, we try to recover by sending a stop command.
For the initial commands (set block count and the read/write command)
no data will have been transferred. All that we need deal with is
retrying at this point. A failed stop command can be remedied as
above.
If we are unable to recover the card (eg, the card ignores our requests
for status, or we don't recognise the error code) then we immediately
fail the request.
