This patch was first posted on August 30, and hasn't shown up in mainline or vfs/for-next so far. Please apply. Thanks, Andreas -- In generic_file_llseek_size, return -ENXIO for negative offsets as well as offsets beyond EOF. This affects filesystems which don't implement SEEK_HOLE / SEEK_DATA themselves, possibly because they don't support holes. Fixes xfstest generic/448.
