[PATCH 049/145] xfs: enable the rmap btree functionality

[Darrick J. Wong]

From: Dave Chinner <dchinner at redhat.com>

Add the feature flag to the supported matrix so that the kernel can
mount and use rmap btree enabled filesystems

v2: Move the EXPERIMENTAL message to fill_super so it only prints once.
