being very lucky with it and not having any problems ! :)
Good work, Bryn!

Hi Bryn,
with this patch and also with 0.415 i have the following problem when
compiling it with stock 2.6.20 :
Building modules, stage 2.
MODPOST 1 modules
WARNING: "invalidate_mapping_pages" [drivers/md/dm-loop.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2
i found , that this was due to missing
EXPORT_SYMBOL(invalidate_mapping_pages);
in mm/truncate.c
i found
http://lkml.org/lkml/2007/1/3/154
it looks that this didn`t go into 2.6.20 and we need at least
2.6.20-git11 ?
changelog at
http://www.kernel.org/pub/linux/kernel/v2.6/snapshots/patch-2.6.20-git11.log
telling that it had just had been merged on 10th of february:
Hi Roland,
That's right - I keep my git tree fairly close to upstream, so as soon
as the patch that deprecated invalidate_inode_pages was merged, I
converted dm-loop to use invalidate_mapping_pages instead.
This means that dm-loop will build without warnings on the latest
kernel.org tree but it does mean that you will need the additional patch
you referenced if you want to apply it to a plain 2.6.20 kernel.
Kind regards,
Bryn.
