Cover letter [PATCH 00/10] Annotate arguments of memtostr/strtomem with __nonstring
Hi,
The memtostr*() and strtomem*() helpers are designed to move between C strings (NUL-terminated) and byte arrays (that may just be zero padded and may not be NUL-terminated). The "nonstring" attribute is used to annotated these kinds of byte arrays, and we can validate the annotation on the arguments of the helpers. Add the the infrastructure to do this, and then update all the places where these annotations are currently missing.
