Al Viro recently gave a hint that he have patches for sparse to not give
spurious ARRAY_SIZE warnings.
I do. Right now it's either 2 or 4 patches away from mainline sparse,
depending on reordering... I'm splitting the last patch in series,
hopefully will reorder and send tonight.
Basically, it's a matter of getting __builtin_compatible_types_p()
implementation (really - evaluate.c:type_difference()) somewhere sane.
Try git://git.kernel.org/pub/scm/linux/kernel/git/viro/sparse.git/,
the branch is type_difference
ok a proper fix is always better than a workaround ;)
it seems that ARRAY_SIZE is defined multiple times....
seem wrong... shouldn't all users include linux/kernel.h and use that one?
