From 4fcc94d653270fcc7800dbaf3b11f78cb462b293 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Thu, 14 Jul 2022 11:38:54 +1000 Subject: xfs: track the iunlink list pointer in the xfs_inode Having direct access to the i_next_unlinked pointer in unlinked inodes greatly simplifies the processing of inodes on the unlinked list. We no longer need to look up the inode buffer just to find next inode in the list if the xfs_inode is in memory. These improvements will be realised over upcoming patches as other dependencies on the inode buffer for unlinked list processing are removed. Signed-off-by: Dave Chinner Reviewed-by: Darrick J.
