It might be better to have a flag FIEMAP_EXTENT_NOT_SHARED. Apps which need to know the data is not shared can't safely check !(flags & FIEMAP_EXTENT_SHARED) because of old kernels which don't set the flag.
I'm probably not understanding your point. Won't the older kernels not set FIEMAP_EXTENT_NOT_SHARED too. If this is important, we could always add this flag in the stable kernel trees. Both sharing of extents and fiemap are relatively new to the kernel. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
