Hi Linus,

The following changes since commit de12c3391bce10504c0e7bd767516c74110cfce1:

  add struct fd constructors, get rid of __to_fd() (2024-08-12 22:01:15 -0400)

  bpf: convert bpf_token_create() to CLASS(fd, ...) (2024-09-12 18:58:02 -0700)

----------------------------------------------------------------
Since Al's first 3 patches for struct_fd landed in
https://lore.kernel.org/all/20240923034731.GF3413968@ZenIV/

This pull includes struct_fd BPF changes from Al and Andrii.

Note the pull includes Andrii's merge commit for Al's
vfs/stable-struct_fd branch with 3 already landed patches
that Andrii applied back in August when Al created
the stable branch. These 8 patches were developed on top.

The last minute rebases are frown upon, so we didn't rebase
and I don't see a way in git to avoid this extra commit.

fwiw the rebased commits are in bpf-next/struct_fd_latest
branch in unlikely case you prefer that.

The following diff stat is concatenated from two 'git request-pull'
commands, since I couldn't make it to generate both patch list
and diff stat correctly. Either patch list was ok or diff stat.
I hope that's ok, since doing
'git pull bpf-next.git tags/bpf-next-6.12-struct-fd'
gives me exactly this result.

There should be no conflicts.
