I've just tried yaffs (2007-12-14 vintage) on 2.6.27 instead of 2.6.25 where it was OK, and it seems that put_inode is no longer a feature of super_operations struct. Has anyone already fixed up 2.6.27 or do I need to work this out? Wookey -- Principal hats: Balloonz - Toby Churchill - Aleph One - Debian http://wookware.org/
