From 3e57ecf640428c01ba1ed8c8fc538447ada1715b Mon Sep 17 00:00:00 2001 From: Olaf Weber 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.

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.
