PRAMFS with XIP support

PRAMFS with XIP support

[Marco Stornelli]

Hi all,

I enjoyed to make a porting of pramfs to the kernel 2.6.26.5. In
addition, I made a patch to add execute-in-place support. You can
download the patches from the project site under "tracker/patches". If
you have comments and/or suggestions you can write to me an email :).
Thanks.

Regards,

Hi Mike,

I am not the PRAMFS mantainer, and I think he is in charge to do that
(right?), I sent an email to Steve Longerbeam and to MontaVista support,
but I haven't received any response. However, if you think it could be
useful to submit it to lkml I could do it.

Regards.

If you don't hear anything within 2 weeks, just submit it.
I've worked with PRAMFS in the past, and I think it's not
a high enough profile project at MontaVista that they'd
be upset if it got mainlined by someone besides Steve.

IRRC, Steve Johnson of Panasonic tried to mainline it a
few years ago, and no one from MV complained.

/me looks up .. 

I'm not familiar with PRAMFS , but I'm sure any contribution or support
is welcome.. I'd be happy to help if anyone wants it.

Thanks Tim and Daniel. Daniel the first thing to do to submit the
patches is check them to verify that they are compliant to the kernel
standard, if you'd like to help you are welcome.

Since the feature was already submitted once (or twice even) I'd image
there is a record of people comments in the list archives .. That should
give a better idea of what needs to be changed ..

I looked at the code on the sourceforge page, and I saw a few clean ups
that could happen. Otherwise, it didn't look bad in terms of code
quality.

Ok, it's a good idea. Thanks.

I'd really like to see this.

If they weren't recent, i.e. 2.6.26, they might not be too relevant.
The XIP framework changed a lot then.
