dchagin 2009-05-25 14:36:21 UTC FreeBSD src repository Modified files: (Branch: RELENG_7) sys/compat/linux linux_emul.c linux_emul.h linux_futex.c Log: 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.
