Hi folks, This is the 4th version of this series to followup on review comments from Brian and Christoph. There are three new patches in this series. Patch 2/8 is split out from patch 3/8 to document the removal of the ioend cancelling code, spearate from the introduction of the writepage context. Patches 7 and 8 are new patches (as in the first time I've posted them) to demonstrate how to remove the IO completion dependency on recording the bufferehads attached to the ioend. This is the first step in removing bufferheads from the writepage IO path - these are FYI patches, not patches I want to have committed immediately. The changes all run through xfstests on 4k and 1k block size filesystems fine, and I think i addressed all the review comments. Patch 6/8 changed enough that I removed Brian's reviewed-by from it and so it will need to be looked at completely again. -Dave. Version 4: - split xfs_ioend_cancel removal into it's own patch (patch 2) - cleaned up submission of ioends to be consistent w.r.t. success and error paths (patch 3) - made variables names less verbose (patch 6) - got rid of xfs_writepage_submit() (patch 6) - use a struct list_head for ioend chaining (patch 6) - consolidated ioend submission paths to use common code (patch 6) _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
