[PATCH AUTOSEL 4.14 20/21] tmpfs: make lseek(SEEK_DATA/SEK_HOLE) return ENXIO with a negative offset

From: Yufen Yu [ Upstream commit 1a413646931cb14442065cfc17561e50f5b5bb44 ] Other filesystems such as ext4, f2fs and ubifs all return ENXIO when lseek (SEEK_DATA or SEEK_HOLE) requests a negative offset. man 2 lseek says : EINVAL whence is not valid. Or: the resulting file offset
