[PATCH 1/1] xfs: add a realtime flag to the bmap update log redo items

Darrick J. Wong

From: Darrick J. Wong <djwong@kernel.org>

Extend the bmap update (BUI) log items with a new realtime flag that
indicates that the updates apply against a realtime file's data fork.
We'll wire up the actual code later.
