SubjectRe: [patch 1/7] procfs: Add ability to plug in auxiliary fdinfo providers
> This patch brings ability to print out auxiliary data associated
> with file in procfs interface /proc/pid/fdinfo/fd.
>
> In particular further patches make eventfd, evenpoll, signalfd
> and fsnotify to print additional information complete enough
> to restore these objects after checkpoint.
>
> To simplify the code we add show_fdinfo callback inside
> struct file_operations (as Al and Pavel are proposing).
