Hi Matthew,

After merging the ida tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

lib/test_xarray.c: In function 'xa_alloc_value':
lib/test_xarray.c:39:16: error: implicit declaration of function 'xa_alloc'; did you mean 'ida_alloc'? [-Werror=implicit-function-declaration]
  XA_BUG_ON(xa, xa_alloc(xa, &id, xa_mk_value(index), GFP_KERNEL) != 0);
                ^
lib/test_xarray.c:21:6: note: in definition of macro 'XA_BUG_ON'
  if (x) {      \
      ^

Caused by commit

  1af163b61ed6 ("xarray: Track free entries in an XArray")

I have reverted that commit for today (and the following one).
