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.
