I was wondering if GFS will run on the 2.6.5 kernel? Currently it won't work because the function: unmap_shared_mapping_range() came into being in the 2.6.6 kernel. It appears that Daniel Phillips created this. Should I be able to take the BitKeeper patch changeset that added this to 2.6.6 and apply it to 2.6.5? Thanks for any info. John
