2006-02-01[PATCH] Direct Migration V9: Avoid writeback / page_migrate() methodChristoph Lameter
Migrate a page with buffers without requiring writeback This introduces a new address space operation migratepage() that may be used by a filesystem to implement its own version of page migration. A version is provided that migrates buffers attached to pages. Some filesystems (ext2, ext3, xfs) are modified to utilize this feature. The swapper address space operation are modified so that a regular migrate_page() will occur for anonymous pages without writeback (migrate_pages forces every anonymous page to have a swap entry).

2006-01-11[XFS] xfssyncd is responsible for flushing inode or device's data byYingping Lu
extracting the work from its queue. In addition, this processing also decrement the inode's i_count. If there are any remaining works in queue before this process terminates, we have unbalanced increment and decrement of i_count. Thus it can cause assertion failure of vn_count. The fix allows xyssyncd to process any remaining work before it is shutdown.
