Hi,
Does the Linux kernel support POSIX message queues as defined by
the Single Unix Specification, v2, ie.
http://www.opengroup.org/onlinepubs/007908799/xsh/mqueue.h.html
stuff like mq_open(), mq_send(), mq_close(), etc.
I've tried grepping the sources for 2.4.0, and could not find anything.

Yep, there's a solution for this. Get yourself the

I have tracked down why I am getting the oops with page->mapping == 0
in block_read_full_page. Well, at least if not the ultimate cause,
then the penultimate cause. It's basically yet another truncate bug
(tm). I have some fairly detailed traces which I can send you if you
like, but
Today I've found the following in my /var/log/messages:

While this subject is fresh, what would be wrong with using the
entire drive as opposed to creating a partition and adding the
partition to the raid?
Does it autodetect an entire drive? The autodetect logic for
partitions looks at the 'partition type' byte, which of course
Just thought others besides Alan would want to know. There's some new data

I have attached a very small patch (test9) to remove the kernel lock from
kernel/acct.c. If I am missing something major (a brain?), I apologise in
advance. I have tested this on my UP x86 with spinlock debugging. I would
appreciate comments or an explanation of why this can't be done if you have
