When I need a ramdisk, I usually do it this way:
* Use "dd if=/dev/zero ..." to create a large file in tmpfs, which can
use swap but will behave like a ramdisk as long as there's memory for it.
* Make the file appear as a disk using losetup.
* Use mkfs on the pseudo-disk and mount it.
The semantics, therefore, are the semantics of whatever filesystem you
used to format the pseudo-disk. That includes xattrs if you used ext4,
