# Merge: 69d5b97c5973 3a08cd52c37c

#     Merge branch 'xarray' of git://git.infradead.org/users/willy/linux-dax
#     
#     Pull XArray conversion from Matthew Wilcox:
#      "The XArray provides an improved interface to the radix tree data
#       structure, providing locking as part of the API, specifying GFP flags
#       at allocation time, eliminating preloading, less re-walking the tree,
#       more efficient iterations and not exposing RCU-protected pointers to
#       its users.
#     
#       This patch set
#     
#        1. Introduces the XArray implementation
#     
#        2. Converts the pagecache to use it
#     
#        3. Converts memremap to use it
#     
#       The page cache is the most complex and important user of the radix
#       tree, so converting it was most important. Converting the memremap
#       code removes the only other user of the multiorder code, which allows
#       us to remove the radix tree code that supported it.
#     
#       I have 40+ followup patches to convert many other users of the radix
#       tree over to the XArray, but I'd like to get this part in first. The
#       other conversions haven't been in linux-next and aren't suitable for
#       applying yet, but you can see them in the xarray-conv branch if you're
#       interested"
