From 3e57ecf640428c01ba1ed8c8fc538447ada1715b Mon Sep 17 00:00:00 2001
From: Olaf Weber <olaf@sgi.com>
Date: Fri, 9 Jun 2006 14:48:12 +1000
Subject: [XFS] Add parameters to xfs_bmapi() and xfs_bunmapi() to have them
report the range spanned by modifications to the in-core extent map. Add
XFS_BUNMAPI() and XFS_SWAP_EXTENTS() macros that call xfs_bunmapi() and
xfs_swap_extents() via the ioops vector. Change all calls that may modify the
in-core extent map for the data fork to go through the ioops vector. This
allows a cache of extent map data to be kept in sync.

From d210a28cd851082cec9b282443f8cc0e6fc09830 Mon Sep 17 00:00:00 2001
From: Yingping Lu <yingping@sgi.com>
Date: Fri, 9 Jun 2006 14:55:18 +1000
Subject: [XFS] In actual allocation of file system blocks and freeing extents,
the transaction within each such operation may involve multiple locking of
AGF buffer. While the freeing extent function has sorted the extents based on
AGF number before entering into transaction, however, when the file system
space is very limited, the allocation of space would try every AGF to get
space allocated, this could potentially cause out-of-order locking, thus
deadlock could happen. This fix mitigates the scarce space for allocation by
setting aside a few blocks without reservation, and avoid deadlock by
maintaining ascending order of AGF locking.
