Subject: [PATCH 0/3] coccinelle: catchup on memory allocation functions

Hi,

Please find few patches that remove coccicheck's blindness
regarding the following functions:
- kzfree()
- krealloc()
- __krealloc()
- devm_kmalloc()
- devm_kvasprintf()
- devm_kasprintf()
- devm_kmalloc_array()
- devm_kcalloc()
- devm_kstrdup()
- devm_kmemdup()
- devm_get_free_pages()
- free_pages()
- free_page()

I've ran coccicheck on drivers/staging and found no new issue,
which is great, but that questions those patches' usefulness,
YMMV.

Regards.

Yann Droneaud (3):
  coccinelle: also catch kzfree() issues
  coccinelle: recognize more devm_* memory allocation functions
  coccinelle: catch krealloc() on devm_*() allocated memory
