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

Christian Brauner christian@brauner.io 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

v1: unchanged v2:

• Christian Brauner christian@brauner.io:
  • verify that close_range() correctly closes a single file descriptor

v3:

• Christian Brauner christian@brauner.io:
  • add missing Cc for Shuah
  • add missing Cc for linux-kselftest

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