From 9817aa80dcdc0358226f41322e1ff35339d0d24b Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Fri, 1 May 2020 16:00:48 -0700 Subject: xfs: refactor log recovery EFI item dispatch for pass2 commit functions Move the extent free intent and intent-done pass2 commit code into the per-item source code files and use dispatch functions to call them. We do these one at a time because there's a lot of code to move. No functional changes. Signed-off-by: Darrick J.
