From f27059065f9996ccda13b495a5838273282a59a1 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 1 Sep 2021 10:46:53 -0700 Subject: xfs: add a realtime flag to the bmap update log redo items 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. Signed-off-by: Darrick J.
