From 154c733a33d9cdaabec42ae76ca1189044d0447e Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Fri, 1 May 2020 16:00:54 -0700 Subject: xfs: refactor releasing finished intents during log recovery Replace the open-coded AIL item walking with a proper helper when we're trying to release an intent item that has been finished. We add a new ->iop_match method to decide if an intent item matches a supplied ID. Signed-off-by: Darrick J.
