[PATCH 0/8] MMC-core: Fine-tuning for some function implementations

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 8 Jan 2017 22:30:03 +0100

Some update suggestions were taken into account
from static source code analysis.

Markus Elfring (8):
  Use kmalloc_array() in mmc_test_area_init()
  Fix a typo in a comment line
  Use seq_puts() in mtf_testlist_show()
  mmc_test: Add some spaces for better code readability
  mmc_test: Combine substrings for 5 messages
  mmc_test: Improve a size determination in five functions
  Use kcalloc() in mmc_test_alloc_mem()
  Use kmalloc_array() in mmc_alloc_sg()

[PATCH 1/8] mmc-core: Use kmalloc_array() in mmc_test_area_init()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 8 Jan 2017 18:44:26 +0100

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kmalloc_array".

  This issue was detected by using the Coccinelle software.

* Replace the specification of a data structure by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.

Chunyan has been running this test code so she might have additional
insights to provide. I am not aware about anyone else really running the
tests, are there people who do it?

I talked about mmc_test on #armlinux channel with a person whose
nickname was s84 other day. It seemed that s84 was also trying to use
mmc_test module.

[PATCH 3/8] mmc-core: Use seq_puts() in mtf_testlist_show()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 8 Jan 2017 19:48:28 +0100

The script "checkpatch.pl" pointed information out like the following.

WARNING: Prefer seq_puts to seq_printf

Thus fix the affected source code place.

[PATCH 6/8] mmc/core/mmc_test: Improve a size determination in five functions

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 8 Jan 2017 21:25:44 +0100

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

[PATCH 7/8] mmc-core: Use kcalloc() in mmc_test_alloc_mem()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 8 Jan 2017 21:43:12 +0100

* The script "checkpatch.pl" pointed information out like the following.

  WARNING: Prefer kcalloc over kzalloc with multiply

  Thus fix the affected source code place.

* Replace the specification of a data structure by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.

[PATCH 8/8] mmc-core: Use kmalloc_array() in mmc_alloc_sg()

[SF Markus Elfring]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 8 Jan 2017 22:10:40 +0100

* A multiplication for the size determination of a memory allocation
  indicated that an array data structure should be processed.
  Thus use the corresponding function "kmalloc_array".

  This issue was detected by using the Coccinelle software.

* Replace the specification of a data structure by a pointer dereference
  to make the corresponding size determination a bit safer according to
  the Linux coding style convention.
