| |
Fixes "Compiler Attributes: add __alloc_size() for better bounds checking" so that the __alloc_size() macro is ignored for function prototypes when generating kerndoc. Avoids warnings like:
./include/linux/slab.h:662: warning: Function parameter or member '1' not described in '__alloc_size' ./include/linux/slab.h:662: warning: Function parameter or member '2' not described in '__alloc_size' ./include/linux/slab.h:662: warning: expecting prototype for kcalloc(). Prototype was for __alloc_size() instead
