The Xarray allows us to store the cached mkeys in memory efficient way. Entries are reserved in the Xarray using xa_cmpxchg before calling to the upcoming callbacks to avoid allocations in interrupt context. The xa_cmpxchg can sleep when using GFP_KERNEL, so we call it in a loop to ensure one reserved entry for each process trying to reserve.
