* [PATCH] Direct Migration V9: Avoid writeback / page_migrate() methodChristoph Lameter2006-02-012-0/+2
| | | | | | | | | | | | | | | | | | | 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).

| * [XFS] Initial pass at going directly-to-bio on the buffered IO path. ThisChristoph Hellwig2006-01-114-364/+431
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] per-mountpoint noatime/nodiratimeChristoph Hellwig2006-01-101-0/+3
| | | | | | | | | | | | | | | | | | | | Turn noatime and nodiratime into per-mount instead of per-sb flags. After all the preparations this is a rather trivial patch. The mount code needs to treat the two options as per-mount instead of per-superblock, and touch_atime needs to be changed to check the new MNT_ flags in addition to the MS_ flags that are kept for filesystems that are always noatime/nodiratime but not user settable anymore. Besides that core code only nfs needed an update because it's leaving atime updates to the server and thus sets the S_NOATIME flag on every inode, but needs to know whether it's a real noatime mount for an getattr optimization. While we're at it I've killed the IS_NOATIME/IS_NODIRATIME macros that were only used by touch_atime.

Also get rid of the unused second argument - we always want to update the ctime when calling this routine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch add EXPORT_SYMBOL(filemap_write_and_wait) and use it. See mm/filemap.c: And changes the filemap_write_and_wait() and filemap_write_and_wait_range(). Current filemap_write_and_wait() doesn't wait if filemap_fdatawrite() returns error. However, even if filemap_fdatawrite() returned an error, it may have submitted the partially data pages to the device. (e.g. in the case of -ENOSPC) <quotation> Andrew Morton writes, If filemap_fdatawrite() returns an error, this might be due to some I/O problem: dead disk, unplugged cable, etc. Given the generally crappy quality of the kernel's handling of such exceptions, there's a good chance that the filemap_fdatawait() will get stuck in D state forever. </quotation> So, this patch doesn't wait if filemap_fdatawrite() returns the -EIO. Trond, could you please review the nfs part? Especially I'm not sure, nfs must use the "filemap_fdatawrite(inode->i_mapping) == 0", or not.
