[LTP] [PATCH 0/8] fanotify tests for v5.13

[Petr Vorel <pvorel@suse.cz>]

Hi Amir,

> Hi Petr,

> Following tests were used for development of the two features
> queued for v5.13 (in linux-next):
> - Performance improvements for events merge [1]
> - Unprivileged fanotify listener [2]

As these are features not fixes, I suppose nothing from these already merged 2
patchsets in next tree can be added with struct tst_tag to document it.
I wonder if any of these are could be at least noted in the tests / commit
messages.

> All test cases of fanotify05 pass on upstream, but their runtime
> on linux-next is reduced by more than half.

> Only the first test case of fanotify17 pass on upstream.
> The rest of the test cases as well as fanotify18 and fanotify19
> tests exit with TCONF on upstream. They all pass on linux-next.

Thanks! LGTM, thanks for testing them on both mainline and next tree.

To whole patchset:
Reviewed-by: Petr Vorel <pvorel@suse.cz>

I'll apply it with following tiny fixes to fix compilation on very old kernels
(2.6.x) and to use our documentation format [3] [4].
(+ later I'll fix documentation format for the rest of the tests)

Kind regards,
Petr
