I mean, normally rds is used to act as a communication protocol between Oracle databases. Now in this patch series, it seems that rds acts as a communication protocol to support a filesystem. So I am curious which filesystem that rds is supporting? The peer here is a file-server which acts a block device. What Oracle calls a cell-server. The initiator here, is actually using XFS over an Oracle in-kernel pseudo-volume block device. Thxs, Håkon
