> Subject: [PATCH 2/2] selftests: add tests for CLOSE_RANGE_CLOEXEC You really ought to check that it skips closed files. For instance using dup2() to move some open files to 'big numbers'. Although you know how it works, a 'black box' test would also reduce RLIMIT_NOFILES below one of the open files and check files above the RLIMIT_NOFILES value are affected.
