Message-ID: <20040407120720.6b937deb.akpm@osdl.org> (raw)
Manfred, if/when this gets merged up the long-suffering arch maintainers
might appreciate a little test app to exercise the syscalls which must be
added. Do you have something suitable at hand?
Also, before we go too far the 64-bit guys may like to comment on the
syscall interface. For example, this:
struct mq_attr {
long mq_flags; /* message queue flags */
long mq_maxmsg; /* maximum number of messages */
long mq_msgsize; /* maximum message size */
long mq_curmsgs; /* number of messages currently queued */
long __reserved[4]; /* ignored for input, zeroed for output */
};
looks like it will require emulation for 32-bit apps. But if we were to
make these __u32 perhaps that could be avoided?
