From 3ec6efa703cf65887e681d1f97d38a63261d907e Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Fri, 1 May 2020 16:00:48 -0700 Subject: [PATCH] xfs: refactor log recovery icreate item dispatch for pass2 commit functions Move the log icreate item pass2 commit code into the per-item source code files and use the dispatch function to call it. We do these one at a time because there's a lot of code to move. No functional changes. Signed-off-by: Darrick J.
