From 23fb5a93c21f7b2393c216b40afff8027164d8d4 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 1 Sep 2020 10:55:20 -0700 Subject: xfs: refactor xfs_buf_ioend Move the log recovery I/O completion handling entirely into the log recovery code, and re-arrange the normal I/O completion handler flow to prepare to lifting more logic into common code in the next commits.
