Gulp!

When I brought this up I was certain that I couldn't get Dave's series to apply
without Christoph's.  Now it works just fine like so:

~/xfs # cat patches/series
# from christoph
xfs-implement-update_time.patch

# from dave  
xfs-fix-allocbt-cursor-leak-in-xfs_alloc_ag_vextent_near.patch

# Mark's patches
xfs-rename-log-structure-and-remove-xlog_t-typedef.patch
tmp.eUYwHqCBlD-2

# seek data seek hole with unwritten extents
xfs-probe-data-buffer-from-page-cache-for-unwritten-extents.patch

# from Alain
prefix-io_xx-flags-with-xfs_io_xx-to-avoid-namespace-colision.patch

# jan's patch is gonna get a new rev
xfs-fix-overallocation-in-xfs_buf_allocate_memory.patch
# dave's patches 
xfs-separate-buffer-indexing-from-block-map.patch
xfs-convert-internal-buffer-functions-to-pass-maps.patch
xfs-add-discontiguous-buffer-map-interface.patch
xfs-add-discontiguous-buffer-support-to-transactions.patch
xfs-struct-xfs_buf_log_format-isn-t-variable-sized.patch
xfs-support-discontiguous-buffers-in-the-xfs_buf_log_item.patch
xfs-use-multiple-irec-xfs-buf-support-in-dabuf.patch
xfs-remove-struct-xfs_dabuf-and-infrastructure.patch
xfs-factor-buffer-reading-from-xfs_dir2_leaf_getdents.patch

# christoph's patches
xfs-kill-xfs_ialloc_find_free
xfs-split-xfs_dialloc
xfs-simplify-xfs_dialloc
xfs-dialloc-shortcut-second-call
xfs-cleanup-xfs_ialloc_ag_select
xfs-dialloc-cleanup-ag-loop-2
xfs-dialloc-factor-ag_selection-2

# from Jan Englehardt
types.h-implement-intptr_t-and-uintptr_t.patch
xfs-use-standard-u-intptr_t-types.patch

So it appears there is no need to rebase Dave's series.  Apologies!  I got it
wrong, not sure how.
