A very large part of extendfs functionality is in the file system, like 100%. Doing this is user space is going to have some challenges, like there several items that aren't exported by the file system (i.e. creating a transaction, .....) Here is a version of jfs_extendfs.c that I'm in the process of porting. It still doesn't compile yet, hopefully it will soon. http://oss.software.ibm.com/developer/opensource/jfs/project/pub/jfs_extendfswip.c Does the extendfs functionality need to be in user space? or can this functionality be in the file system and just be called from your user space program?
