I think this looks good, but can you confirm that |

I think this should be @rustbot ready If you have a link to the headers / docs that would be great, trying to get them linked in every PR so we can find them again when needed. |

https://github.com/torvalds/linux/blob/0c3836482481200ead7b416ca80c68a29cfdaabd/include/uapi/linux/fanotify.h#L153 doesn't seem to have an alignment attribute, and I think the default alignment should naturally be 16 bits. Why is it needed here?

Also I think this would cause a problem building on ancient versions with alignment since this doesn't have a fallback

Why are these GNU-only? I don't see them reexported in glibc, only uapi

it s a bit of a mess on musl. with glibc it s enough to include sys/fanotify.h which in turn include linux/fanotify.h so you have all you need for this. in musl sys/fanotify.h which does not include linux/fanotify.h and if you do include both there are couple of type redefinition conflicts.
