Pavel Emelyanov 48f6a7a511 posix-timers: Introduce /proc/PID/timers file ... Currently kernel doesn't provide any API for getting info about what posix timers are configured by processes. It's implied, that a process which configured some timers, knows what it did. However, for external tools it's impossible to get this information. In particular, this is critical for checkpoint-restore project to have this info. Introduce a per-pid proc file with information about posix timers. Since these timers are shared between threads, this file is present on tgid level only, no such thing in tid subdirs. The file format is expected to be the "/proc/<pid>/smaps"-like, i.e. each timer will occupy seveal lines to allow for future extending. Each new timer entry starts with the ID: <number> line which is added by this patch.
