Subject: linux-next: build failure after merge of the xarray tree

Hi all,

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

lib/test_xarray.c: In function 'check_xa_mark_3':
lib/test_xarray.c:305:3: error: implicit declaration of function 'assert' [-Werror=implicit-function-declaration]
  305 |   assert(1);
      |   ^~~~~~
lib/test_xarray.c:11:1: note: 'assert' is defined in header '<assert.h>'; did you forget to '#include <assert.h>'?
   10 | #include <linux/module.h>
  +++ |+#include <assert.h>
   11 | 

Caused by commit

  5c8052d7925b ("XArray test: Add new test")

I have added the following hack for today:
