* [XFS] Fix nused counter. It's currently getting set to -1 rather thanMandy Kirkconnell2006-06-09
| | | | | | | | | | | | | | getting decremented by 1. Since nused never reaches 0, the "if (!free->hdr.nused)" check in xfs_dir2_leafn_remove() fails every time and xfs_dir2_shrink_inode() doesn't get called when it should. This causes extra blocks to be left on an empty directory and the directory in unable to be converted back to inline extent mode.

* [XFS] In actual allocation of file system blocks and freeing extents, theYingping Lu2006-06-09
| | | | | | | | | | | | | | | | | 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.
