What happened:
How to Repoduce:

# git checkout test-acl
# python3 .github/scripts/hypo/fsrand2_test.py -k test_acl

Test Code:

    def test2(self):
        state = JuicefsMachine()
        v1 = state.init_folders()
        v3 = state.set_acl(default=True, entry=v1, group='root', group_perm=set(), logical=False, mask=set(), not_recalc_mask=False, other_perm=set(), physical=False, recalc_mask=True, recursive=True, rootdir1='/tmp/fsrand', rootdir2='/tmp/jfs/fsrand', set_mask=True, sudo_user='root', user='user1', user_perm={v1, 'r', 'w', 'x'})
        state.create_file(content=b'', file_name='afds', mode='w', parent=v1, rootdir1='/tmp/fsrand', rootdir2='/tmp/jfs/fsrand', umask=295, user='root')
        state.teardown()

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?

Environment:

• JuiceFS version (use juicefs --version) or Hadoop Java SDK version:
• Cloud provider or hardware configuration running JuiceFS:
• OS (e.g cat /etc/os-release):
• Kernel (e.g. uname -a):
• Object storage (cloud provider and region, or self maintained):
• Metadata engine info (version, cloud provider managed or self maintained):
• Network connectivity (JuiceFS to metadata engine, JuiceFS to object storage):
• Others:
