[PATCH] posix message queues: syscall stubs
From: Manfred Spraul <manfred@colorfullife.com> Add -ENOSYS stubs for the posix message queue syscalls. The API is a direct mapping of the api from the unix spec, with two exceptions: - mq_close() doesn't exist. Message queue file descriptors can be closed with close(). - mq_notify(SIGEV_THREAD) cannot be implemented in the kernel. The kernel returns a pollable file descriptor . User space must poll (or read) this descriptor and call the notifier function if the file descriptor is signaled.
