2006-03-26[PATCH] remove ->get_blocks() supportBadari Pulavarty
Now that get_block() can handle mapping multiple disk blocks, no need to have ->get_blocks(). This patch removes fs specific ->get_blocks() added for DIO and makes it users use get_block() instead.

2006-03-26[PATCH] map multiple blocks for mpage_readpages()Badari Pulavarty
This patch changes mpage_readpages() and get_block() to get the disk mapping information for multiple blocks at the same time. b_size represents the amount of disk mapping that needs to mapped. On the successful get_block() b_size indicates the amount of disk mapping thats actually mapped. Only the filesystems who care to use this information and provide multiple disk blocks at a time can choose to do so. No changes are needed for the filesystems who wants to ignore this.

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] clean up the xfs_offset_to_map interface Currently we pass a structChristoph Hellwig
page and a relative offset into that page around, and returns the current xfs_iomap_t if the block at the specified offset fits into it, or a NULL pointer otherwise.

2006-01-11[XFS] Initial pass at going directly-to-bio on the buffered IO path. ThisChristoph Hellwig
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.

2005-10-28[PATCH] gfp_t: fs/*Al Viro
- ->releasepage() annotated (s/int/gfp_t), instances updated - missing gfp_t in fs/* added - fixed misannotation from the original sweep caught by bitwise checks: XFS used __nocast both for gfp_t and for flags used by XFS allocator. The latter left with unsigned int __nocast; we might want to add a different type for those but for now let's leave them alone. That, BTW, is a case when __nocast use had been actively confusing - it had been used in the same code for two different and similar types, with no way to catch misuses. Switch of gfp_t to bitwise had caught that immediately... One tricky bit is left alone to be dealt with later - mapping->flags is a mix of gfp_t and error indications. Left alone for now.
