 ### Changed 
   - Tests check ret for -1 instead of 10000 fd ([!320](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/320))
     - Allow some more script tests to run as pthread_at_fork solved some issues.
-    
+  - Return EINVAL is better than ENOTSUP on internal readlink ([!223](https://storage.bsc.es/gitlab/hpc/gekkofs/-/merge_requests/223))
