#     Merge tag 'xarray-5.1-rc1' of git://git.infradead.org/users/willy/linux-dax
#     
#     Pull XArray updates from Matthew Wilcox:
#      "This pull request changes the xa_alloc() API. I'm only aware of one
#       subsystem that has started trying to use it, and we agree on the fixup
#       as part of the merge.
#     
#       The xa_insert() error code also changed to match xa_alloc() (EEXIST to
#       EBUSY), and I added xa_alloc_cyclic(). Beyond that, the usual
#       bugfixes, optimisations and tweaking.
#     
#       I now have a git tree with all users of the radix tree and IDR
#       converted over to the XArray that I'll be feeding to maintainers over
#       the next few weeks"
