signalfd: fill in ssi_int for posix timers and message queues
If signalfd is used to consume a signal generated by a POSIX interval
timer or POSIX message queue, the ssi_int field does not reflect the data
(sigevent->sigev_value) supplied to timer_create(2) or mq_notify(3). (The
ssi_ptr field, however, is filled in.)
This behavior differs from signalfd's treatment of sigqueue-generated
signals -- see the default case in signalfd_copyinfo. It also gives
results that differ from the case when a signal is handled conventionally
via a sigaction-registered handler.
So, set signalfd_siginfo->ssi_int in the remaining cases (__SI_TIMER,
__SI_MESGQ) where ssi_ptr is set.
akpm: a non-back-compatible change. Merge into -stable to minimise the
number of kernels which are in the field and which miss this feature.
