Summary
mm/huge_memory: Fix xarray node memory leak
Details

In the Linux kernel, the following vulnerability has been resolved:

mm/huge_memory: Fix xarray node memory leak

If xassplitalloc() fails to allocate the necessary nodes to complete the xarray entry split, it sets the xastate to -ENOMEM, which xasnomem() then interprets as "Please allocate more memory", not as "Please free any unnecessary memory" (which was the intended outcome). It's confusing to use xasnomem() to free memory in this context, so call xasdestroy() instead.
