Merge patch series "filesystems selftests cleanups and fanotify test"
Amir Goldstein <amir73il@gmail.com> says:
This adds a test for fanotify mount ns notifications inside userns [1].
While working on the test I ended up making lots of cleanups to reduce
build dependency on make headers_install.
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 [2].
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 selftests
branch for 6.16, so that it can be used to test the fanotify patches.
NOTE #2: some of the defines in wrappers.h are left for overlayfs and
mount_setattr tests, which were not converted to use TOOLS_INCLUDES.
I did not want to mess with those tests.
