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.
