Subject: [PATCH 0/5] XFS: Track reclaimable inodes in inode cache V2.
Date: Tue, 16 Sep 2008 15:06:25 +1000 [thread overview]
Message-ID: <1221541590-28469-1-git-send-email-david@fromorbit.com> (raw)
Move the tracking of reclaimable inodes into the inode radix trees.
This currently does not replace the reclaim flags in the inode,
rather it allows traversal of all reclaimable inodes by walking the
per-AG inode radix trees without needing a separate list. This
enables us to remove a struct list_head from the struct xfs_inode
and the xfs_mount, as well as a filesystem global lock which also
has the benefit of removing a point of serialisation during inode
reclaim.
Like the matching sync code, this also allows reclaim of inodes
in ascending inode numbers which substantially improves I/O
patterns during reclaim driven inode flushing.
Version 2:
o reorder series to put all re-arrangement at the start
o rediff as prior patch set was updated
