Re: [PATCH v3 3/3] tests: add close_range() tests

Christian Brauner [off-list ref] writes:

This adds basic tests for the new close_range() syscall.
- test that no invalid flags can be passed
- test that a range of file descriptors is correctly closed
- test that a range of file descriptors is correctly closed if there there
  are already closed file descriptors in the range
- test that max_fd is correctly capped to the current fdtable maximum

Sorry I replied to v2, but I think my comments still apply:
