Re: [PATCH v3 1/4] IPC: Added two new system call mq_recvmmsg() and mq_sendmmsg()

Hi,

I am resending this due to a mail server error.

I never tested in compat mode. I will do and look at all the points
mentioned above.
I will insist you to please do a complete review and kindly tell me if
any more such or any architecture specific issue exists.

Regarding optimization on target retrieval from tree, can you provide
any suggestion how we can minimize complete traversal required for
each time. if we maintain state how we know the current cache or
stored efficient node belongs to which system calls from userspace if
we assume many concurrent processes calling it.

Thanks,
Mathura
