SVN rev 192759 on 2009-05-25 14:36:21Z by dchagin
Merge r191269 from HEAD to stable/7:
Remove support for FUTEX_REQUEUE operation.
Glibc does not use this operation since 2.3.3 version (Jun 2004),
as it is racy and replaced by FUTEX_CMP_REQUEUE operation.
Glibc versions prior to 2.3.3 fall back to FUTEX_WAKE when
FUTEX_REQUEUE returned EINVAL.
Any application directly using FUTEX_REQUEUE without return
value checking are definitely broken.
Limit quantity of messages per process about unsupported
operation.
