Max Reitz 4f11aa8a40 block/raw-posix: Try both FIEMAP and SEEK_HOLE ... The current version of raw-posix always uses ioctl(FS_IOC_FIEMAP) if FIEMAP is available; lseek with SEEK_HOLE/SEEK_DATA are not even compiled in in this case. However, there may be implementations which support the latter but not the former (e.g., NFSv4.2) as well as vice versa. To cover both cases, try FIEMAP first (as this will return -ENOTSUP if not supported instead of returning a failsafe value (everything allocated as a single extent)) and if that does not work, fall back to SEEK_HOLE/SEEK_DATA.
