Greg KH / Factory, I mostly lurk on the Ext4 kernel mailing list. Just this morning I participated in a brief thread about ext4's newly merged online defrag ioctl which was pushed to Linus in the 2.6.31 merge window and is part of 2.6.31-rc7 at a minimum. As of rc7 there is not a Kconfig option to disable it. Per http://marc.info/?l=linux-ext4&m=124992522305319&w=2, it currently can cause oop'es when defragging a sparse file, and the recently submitted patch to resolve that introduces file corruption of those same files. I don't know if 11.2 had plans of including ex4defrag or not, but if so I believe this issue should be closely watched and may need to be dropped altogether until 11.3 comes along. Even if userspace was not going to have the ex4defrag tool, having the ioctl in the final 11.2 shipping kernel also seems like a bad idea. I hope it gets somehow marked experimental before 2.6.31 goes final. If not Greg KH and his team may need to patch it out of the kernel for our release.
