I've applied this patch, but removed that last paragraph, which doesn't really belong in the permanent changelog. > Fixes: fd5425b67355 ("docs, resolve_btfids: Document kfunc BTF annotation emission") > Assisted-by: Claude This line is no longer required, so I took it out as well. > Signed-off-by: Mark Severson Thanks, jon
