From 5773f7f82be5aa98e4883566072d33342814cebe Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 22 Apr 2024 09:47:42 -0700 Subject: [PATCH] xfs: create attr log item opcodes and formats for parent pointers Make the necessary alterations to the extended attribute log intent item ondisk format so that we can log parent pointer operations. This requires the creation of new opcodes specific to parent pointers, and a new four-argument replace operation to handle renames. At this point this part of the patchset has changed so much from what Allison original wrote that I no longer think her SoB applies. Signed-off-by: Darrick J.
