Linux supports mounting over non-empty directories by default. In Solaris this is not the case and -O option is required for zfs mount to mount a zfs filesystem over a non-empty directory. For compatibility, I've added support for -O option to mount zfs filesystems over non-empty directories if the user wants to, just like in Solaris. I've defined MS_OVERLAY to record it in the flags variable if the -O option is supplied. The flags variable passes through a few functions and its checked before performing the empty directory check in zfs_mount function. If -O is given, the check is not performed.
