Subject: [PATCH 0/4] XFS: replace the mount inode list with radix tree traversals
Date: Sun, 20 Jul 2008 22:19:50 +1000 [thread overview]
Message-ID: <1216556394-17529-1-git-send-email-david@fromorbit.com> (raw)
The list of all inodes on a mount is superfluous. We can traverse
all inodes now by walking the per-AG inode radix trees without
needing a separate list. This enables us to remove a bunch of
complex list traversal code and remove another two pointers from
the xfs_inode.
Also, by replacing the sync traversal with an ascending inode
number traversal, we will issue better inode I/O patterns for
writeback triggered by xfssyncd or unmount.
Diffstat for the change:
