Hi all,

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

In file included from include/linux/slab.h:15,
                 from drivers/md/raid1.c:26:
drivers/md/raid1.c: In function 'alloc_behind_master_bio':
include/linux/gfp.h:320:36: error: passing argument 1 of 'free_pages' makes=
 integer from pointer without a cast [-Werror=3Dint-conversion]

  303 | extern void free_pages(unsigned long addr, unsigned int order);
      |                        ~~~~~~~~~~~~~~^~~~

Caused by commit

  6473bc325644 ("md: check for failure when adding pages in alloc_behind_ma=
ster_bio")

I have used the block tree from next-20230531 for today.
