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. Approved by: kib (mentor) MFC after: 1 month |
