* [PATCH] Direct Migration V9: Avoid writeback / page_migrate() methodChristoph Lameter2006-02-01
| | | | | | | | | | | | | | | | | | | 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).

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.

This patch passed the full 64bit offset into the inode that all callers have anyway, and changes the return value to a simple boolean. Also the function gets a more descriptive name: xfs_iomap_valid.

| * | [XFS] Initial pass at going directly-to-bio on the buffered IO path. ThisChristoph Hellwig2006-01-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | allows us to submit much larger I/Os instead of sending down lots of small buffer_heads. To do this we need to have a rather complicated I/O submission and completion tracking infrastructure. Part of the latter has been merged already a long time ago for direct I/O support. Part of the problem is that we need to track sub-pagesize regions and for that we still need buffer_heads for the time beeing. Long-term I hope we can move to better data strucutures and/or maybe move this to fs/mpage.c instead of having it in XFS.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | was caused by ENOSPC but not Rreclaimed by xfs_release or xfs_inactive. The fix changed the condition in xfs_release and xfs_inactive to invoke xfs_inactive_free_eofblocks for this special case, changed xfs_inactive_free_eofblocks to clean the delayed blks after eof. It also changed xfs_write to set correct eof when ENOSPC occurs.
