[PATCH 0/5] filesystems selftests cleanups

[Amir Goldstein <amir73il@gmail.com>]

Christian,

I was cleaning up my test env today to prepare for the test
of fanotify mount ns notifications inside userns and tried to
disolve the headers_install depenency.

These patches got rid of the dependency for my kvm setup for the
affected filesystems tests.

Building with TOOLS_INCLUDES dir was recommended by John Hubbard [1].

NOTE #1: these patches are based on a merge of vfs-6.16.mount
(changes wrappers.h) into v6.15-rc5 (changes mount-notify_test.c),
so if this cleanup is acceptable, we should probably setup a stable
branch for 6.16, so that I can base my fanotify patches on it.

NOTE #2: some of the defines in wrappers.h are only left for
mount_setattr, which was not converted to use TOOLS_INCLUDES.
I did not want to mess with it.

Thanks,
Amir.
