- Added OpenAFS to whitelist (so users can now mount FUSE filesystems on mountpoints within OpenAFS filesystems).
- Added a test of seekdir to test_syscalls.
- Fixed readdir bug when non-zero offsets are given to filler and the filesystem client, after reading a whole directory, re-reads it from a non-zero offset e. g. by calling seekdir followed by readdir.
