[Linux-kernel-mentees] [PATCH v3 0/3] cocci: Improve management of macros before typedefs

[Jaskaran Singh]

This patch series is for improving the management of the following
case:

<macro> <typedef> <ident>

If <typedef> is a known typedef (such as u8 or *_t) then label <macro> as a
CppMacro. Subsequent cases will continue to label <typedef> correctly as a
typedef identifier.

Also add bool to the list of known typedefs so that cases of

<macro> bool <ident>

are handled correctly just like any known typedef will be.

Changes in v3:
--------------
- Change "subsequent cases will label" to "subsequent cases will continue to
  label" in commit messages of Patch 0/3 and Patch 1/3.
- Change the term "typedef ident" to "typedef identifier" wherever
  suitable.
- Add metavariable symbol false to tests/macro_before_bool.cocci to
  suppress warning.

Changes in v2:
--------------
- Group these patches as a series for clarity
- Add a test case for <macro> bool <ident> (Patch 3/3)
- Explain what has been improved with Patch 2/3
