Only Matthew posted two tests... anyway I don't think merge is going to be a big problem. I am hoping that PIDFD tests could be merged soonish and I recommended Matthew to base his tests over your first two macro prep patches. Thanks, Amir.

Also it'd be nice just to mention relevant commits which added FAN_FS_ERROR in fanotify21.c (probably "fanotify: Allow users to request FAN_FS_ERROR events" ?) + kernel version it added it -suppose 5.16 (although it can be backported; and these commits should not go to .tags, as we track there only fixes not new features). I can add it myself (no need to repost). Kind regards, Petr

No point in doing that. There will be no kernel release which meets the test requirements and has this bug. Thanks, Amir.

Yes, that's correct for stable kernels, enterprise kernels can backport FAN_FS_ERROR feature, while miss this fix (it does not mention Fixes). Kind regards, Petr > Thanks, > Amir.
Hi Gabriel, all, I merged Matthew's v3 FAN_REPORT_PIDFD, which is for 5.15 kernel. Could you please rebase your changes on the top of current master? Unfortunately that means to rename fanotify21.c in all commits.
