Re: [PATCH] uapi: avoid namespace conflict in linux/posix_types.h

* Linus Torvalds:

A different approach would rename <asm/posix_types.h> to something more
basic, exclude the two structs, and move all internal #includes which do
need the structs to the new header.

In fact, I wouldn't even rename <posix_types.h> at all, I'd just make
sure it's namespace-clean.

I _think_ the only thing causing problems is  '__kernel_fsid_t' due to
that "val[]" thing, so just remove ity entirely, and add it to
<statfs.h> instead.

There's also __kernel_fd_set in <linux/posix_types.h>.  I may have
lumped this up with <asm/posix_types.h>, but it has the same problem.

If it's okay to move them both to more natural places (maybe
<asm/statfs.h> and <linux/socket.h>), I think that should work well for
glibc.

However, application code may have to include additional header files.
I think the GCC/LLVM sanitizers currently get __kernel_fd_set from
<linux/posix_types.h> (but I think we discussed it before, they really
shouldn't use this type because it's misleading).

Thanks,
Florian
