centos7 glibc doesn't have it.

/prog_tests/test_local_storage.c:59:8: warning: implicit declaration of function ‘copy_file_range’; did you mean ‘sync_file_range’? [-Wimplicit-function-declaration]

ld: test_local_storage.test.o: in function `copy_rm':
test_local_storage.c:59: undefined reference to `copy_file_range'

Could you use something else or wrap it similar to pidfd_open ?
