Subject: /proc/pid/fdinfo: add cloexec information
From: Ulrich Drepper <drepper@gmail.com>
There is one piece of information about a file descriptor which is
currently not visible from the outside: the close-on-exec flag. The
/proc/PID/fdinfo/* files have the mode information but this is missing.
This is needed so that Linux can re-implement the Solaris pfiles program.
