From 1f23bc7869fffec40b8bd9333a74a18d1de54d98 Mon Sep 17 00:00:00 2001 From: Abhi Das Date: Fri, 22 Dec 2017 07:55:31 -0600 Subject: [PATCH] gfs2: Trim the ordered write list in gfs2_ordered_write() We iterate through the entire ordered writes list in gfs2_ordered_write() to write out inodes. It's a good place to try and shrink the list by throwing out inodes that don't have any pages.
