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" * tag 'xarray-5.1-rc1' of git://git.infradead.org/users/willy/linux-dax: XArray: Fix xa_reserve for 2-byte aligned entries XArray: Fix xa_erase of 2-byte aligned entries XArray: Use xa_cmpxchg to implement xa_reserve XArray: Fix xa_release in allocating arrays XArray: Mark xa_insert and xa_reserve as must_check XArray: Add cyclic allocation XArray: Redesign xa_alloc API XArray: Add support for 1s-based allocation XArray: Change xa_insert to return -EBUSY XArray: Update xa_erase family descriptions XArray tests: RCU lock prohibits GFP_KERNEL
