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"
