From 966ceafc7a437105ecfe1cadb3747b2965a260ca Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 15 Apr 2024 14:54:17 -0700 Subject: xfs: create deferred log items for file mapping exchanges Now that we've created the skeleton of a log intent item to track and restart file mapping exchange operations, add the upper level logic to commit intent items and turn them into concrete work recorded in the log. This builds on the existing bmap update intent items that have been around for a while now. Signed-off-by: Darrick J.
