These each return the assigned value of ptr (which may be NULL on
failure). For cases where the total size of the allocation is needed,
the kmalloc_obj_sz(), kmalloc_objs_sz(), and kmalloc_flex_sz() family
of macros can be used. For example:
info->size = struct_size(ptr, flex_member, count);
ptr = kmalloc(info->size, gfp);
becomes:
kmalloc_flex_sz(ptr, flex_member, count, gfp, &info->size);
I wonder if it'd be better to keep the gfp flags as the last argument
for all these `*_sz()` cases:
kmalloc_flex_sz(ptr, flex_member, count, &info->size, gpf);
Probably, even for __alloc_objs()
