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,
XFS, etc.
