Hi Petr, Kernel 6.5 and upcoming kernel 6.6 have several improvements to the integration of fanotify and overlayfs. Kernel 6.5 includes the fix to generate fanotify events on watched overlayfs underlying filesystem (tst_variant 1). Kernel 6.5 also added support for the new AT_HANDLE_FID flag, which is used in this test. Kernel 6.6 brings overlayfs support for AT_HANDLE_FID and with it better support for watching overlayfs with fanotify (tst_variant 2). tst_variant 2 is duely skipped on kernel 6.5 and tst_variant 1 is skipped on older kernels. Since the overlayfs changes are not in a release kernel yet, and since this is not a new test that can go to staging tests, I will leave it to you to decide how and when you want to merge these new test variants. Thanks, Amir.
