On newer sysvers the state fields setup by [[#CreateSmmuSpace]] are compared with '''buffer'''. If it's within bounds of the SmmuSpace (which won't be the case when [[#CreateSmmuSpace]] wasn't used), it will then verify that buffer+buffer_size is within bounds throwing an error otherwise.

Note that a buffer from [[#CreateSmmuSpace]] can't be reused by another endpoint with PostBufferAsync.
