[Pvfs2-developers] Fedora 7 patches and build log

[David Brown]

Okay haven't tested this yet as a whole working file system yet, but
it builds and modprobes successfully without bringing down the box...
so here's some of the patches I had to use to make it work.

Fedora 7 is some flavor of 2.6.21 heavily modified as redhat can't
seem to keep things simple...

I think I posted this patch before but here's the rendition I used for fc7
The ${CFLAGS/-O2/} is a bashism and should probably get replaced but
it worked removing the -O2 from the current CFLAGS that rpmbuild loves
to throw in there.

However, this is one that you might want to check out I haven't tried
debian unstable 2.6.21 yet but I'm betting this will need to be
applied there.

========================

The build log shows a bunch of warnings especially in the kernel
module build section... not sure if this is part of the CFLAGS that
rpmbuild throws in or what.

Thanks,
