reiserfs was never updated to set the xattr on newly created files when
that functionality moved from the vfs to the individual filesystems (so
that it could be atomically with the file creation).  And historically
we had numerous problems with the reiserfs xattr-as-files model leading
to deadlocks and permission denials; it wasn't designed or implemented
with MAC labeling in mind.
