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: commit 54bc485522afdac33de5504da2ea8cdcc690674e Author: Anton Altaparmakov <aia21@xxxxxxxxx> Date: Sat Feb 10 01:45:38 2007 -0800 [PATCH] Export invalidate_mapping_pages() to modules It makes no sense to me to export invalidate_inode_pages() and not invalidate_mapping_pages() and I actually need invalidate_mapping_pages() because of its range specification ability... akpm: also remove the export of invalidate_inode_pages() by making it an inlined wrapper. so, we need 2.6.20-git11 for dm-loop or we would need to modify mm/truncate.c manually !? regards roland > -----Ursprüngliche Nachricht----- > Von: "Bryn M.
