scripts: kernel-doc: Ignore __alloc_size() attribute
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 Suggested-by: Matthew Wilcox <willy@infradead.org> Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Kees Cook <keescook@chromium.org> Link: https://lore.kernel.org/r/20211011180650.3603988-1-keescook@chromium.org Signed-off-by: Jonathan Corbet <corbet@lwn.net>
