Subject[PATCH 09/40] UAPI: Make linux/patchkey.h easier to parse [ver #3]
Date
Make linux/patchkey.h easier to parse by:

(1) Switching the reinclusion guard and the indirect-inclusion checks in
linux/patchkey.h to put the guard around the outside.

(2) Making the #elif case associated with the __KERNEL__ guard a nested #if
in a #else of the __KERNEL__ guard.
