"descriptors in I</proc/self/fd/> and calling B<close>(2) on each one. "
"B<close_range>() can take care of this without requiring I</proc> and "
"within a single system call, which provides significant performance benefits."

"This is particularly useful in cases where multiple pre-B<exec> setup steps "
"risk conflicting with each other. For example, setting up a B<seccomp>(2) "
"profile can conflict with a B<close_range>() call: if the file descriptors "
"are closed before the B<seccomp>(2) profile is set up, the profile setup "
"can't use them itself, or control their closure; if the file descriptors are "
"closed afterwards, the seccomp profile can't block the B<close_range>() "
"call or any fallbacks. Using B<CLOSE_RANGE_CLOEXEC> avoids this: the "
"descriptors can be marked before the B<seccomp>(2) profile is set up, and "
