Ocfs2 users - Apr 2006 - shared writable mmap

I'm testing ocfs2 as a root filesystem under Debian, and apt-get barfs
with:

Reading package lists... Error!
E: Couldn't make mmap of 12582912 bytes - mmap (22 Invalid argument)
W: Unable to munmap
E: The package lists or status file could not be parsed or opened.

According to the kernel help files, 'shared writable mmap' isn't yet
supported, which presumably explains the above.

Is this going to be added any time soon? I'm currently using the ocfs2
kernel modules in linux 2.6.16, maybe a later version supports it?

Thanks

James

Presumably.  An strace could verify the cause.

It's on the list of things to do but its relative priority and timing
hasn't been decided, as far as I know.  Unfortunately, doing it well it
requires some changes to the page fault paths in the kernel.  Nothing
serious, but that sort of thing always makes this kind of work take longer.

Not yet, no.
