Thank you for your report.
This issue was already identified and fixed by Sasha[1]. Looks like there
was some problem when my patchest[2] was applied to the git tree:
commit 3e14f079d7a0 ("selftests/fuse: add fuse symlink caching test")
dropped the actual test code that was present in the patch.
I believe Sasha's fix wasn't yet applied, but I guess that will eventually
happen.
