Can we get this made generic like the FIBMAP interface so we don't have to replicate all the copyin/copyout handling and interface definitions everywhere? i.e. a ->extent_map aops callout to the filesystem in generic code just like ->bmap? > I've asked Kalpak to post > an updated version of that patch along with the changes to the "filefrag" > tool to use FIEMAP. Where can I find the test program that validates the implementation? Also, following the fallocate model, can we get the interface definition turned into a man page before anything is submitted upstream?
