vfs: show O_CLOEXE bit properly in /proc/<pid>/fdinfo/<fd> files
...
The CLOEXE bit is magical, and for performance (and semantic) reasons we
don't actually maintain it in the file descriptor itself, but in a
separate bit array. Which means that when we show f_flags, the CLOEXE
status is shown incorrectly: we show the status not as it is now, but as
it was when the file was opened.
Fix that by looking up the bit properly in the 'fdt->close_on_exec' bit
array.
Uli needs this in order to re-implement the pfiles program:
"For normal file descriptors (not sockets) this was the last piece of
information which wasn't available. This is all part of my 'give
Solaris users no reason to not switch' effort. I intend to offer the
code to the util-linux-ng maintainers."
