From d835e7473ac7ea7dcc8b46aed90f5fe7cbabdcbf Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Tue, 28 May 2024 21:11:39 -0700 Subject: [PATCH] xfs: support logging EFIs for realtime extents Teach the EFI mechanism how to free realtime extents. We're going to need this to enforce proper ordering of operations when we enable realtime rmap. Declare a new log intent item type (XFS_LI_EFI_RT) and a separate defer ops for rt extents. This keeps the ondisk artifacts and processing code completely separate between the rt and non-rt cases. Hopefully this will make it easier to debug filesystem problems. Signed-off-by: Darrick J.
