mmc: core: no need to check return value of debugfs_create functions

2019-06-17T11:30:49+00:00

When calling debugfs functions, there is no need to ever check the
return value.  The function can work or not, but the code logic should
never do something different based on this.

mmc: mmc_test: Ensure command queue is disabled for testing

2017-12-11T11:51:29+00:00

mmc_test disables the command queue because none of the tests use the
command queue. However the Reset Test will re-enable it, so disable it in
that case too.

mmc_test: use ktime_get_ts64 for timestamps

2017-12-11T11:48:06+00:00

Calling getnstimeofday() can suffer from time jumps and from the
y2038 overflow, so it is not appropriate here. Using ktime_get_ts64()
solves both problems. Using ktime_get() with ktime_t timestamps would
also work, but it seems that we mainly want to print the times as
seconds+nanoseconds, so it would require an extra division in the output.

mmc: mmc_test: Do not use mmc_start_areq() anymore

2017-12-11T11:44:39+00:00

The block driver's blk-mq paths do not use mmc_start_areq(). In order to
remove mmc_start_areq() entirely, start by removing it from mmc_test.

mmc: test: reduce stack usage in mmc_test_nonblock_transfer

2017-08-30T13:03:37+00:00

The new lockdep annotations for completions cause a warning in the
mmc test module, in a function that now has four 150 byte structures
on the stack:

drivers/mmc/core/mmc_test.c: In function 'mmc_test_nonblock_transfer.constprop':
drivers/mmc/core/mmc_test.c:892:1: error: the frame size of 1360 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

The mmc_test_ongoing_transfer function evidently had a similar problem,
and worked around it by using dynamic allocation.

This generalizes the approach used by mmc_test_ongoing_transfer() and
applies it to mmc_test_nonblock_transfer() as well.

mmc: core: rename mmc_start_req() to *areq()

2017-02-13T12:20:58+00:00

With the coexisting __mmc_start_request(), mmc_start_request()
and __mmc_start_req() it is a bit confusing that mmc_start_req()
actually does not start a normal request, but an asynchronous
request.

Rename it to mmc_start_areq() to make it explicit what the
function is doing, also fix the kerneldoc for this function
while we're at it.
