[PATCH v2 0/4] Update memdup_user.cocci

[Denis Efremov]

Add GFP_USER to the allocation flags and handle vmemdup_user().
The third patch supresses memdup_user(), vmemdup_user() functions
detection. Last patch is a proof of concept for the rule selfchecking.
Gives the ability to detect that an open-coded pattern in a function
definition that we search for in the kernel sources changed.

Denis Efremov (4):
  coccinelle: api: extend memdup_user transformation with GFP_USER
  coccinelle: api: extend memdup_user rule with vmemdup_user()
  coccinelle: api: filter out memdup_user definitions
  coccinelle: api: add selfcheck for memdup_user rule
