[LTP] [PATCH v2 0/3] Tests for fanotify on anonymous pipe

[Amir Goldstein]

Petr,

This tests for a behavior that we consider broken since the dawn of
fanotify.

The fix was merged to v6.5-rc1.
I've already posted backport patches for kernels > v5.0 [1].
I am not planning to post backport patches for older kernels.

Even though the two new test cases do not use FAN_REPORT_FID,
fanotify14 requires FAN_REPORT_FID, so it is not going to run these
test cases on kernel < v5.1 anyway.

You suggested to wait for stable tree to apply the backports [2],
but this seems to be taking time.  Since I am going on vacation next
week, I am posting these tests, so you can merge them whenever you like.

Thanks,
Amir.
