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

Hi all,

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

drivers/md/bcache/btree.c: In function 'bch_btree_check':
drivers/md/bcache/btree.c:2073:1: error: the frame size of 2184 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
 2073 | }
      | ^

Caused by commit

  c766acd3d78e ("bcache: improve multithreaded bch_btree_check()")

struct btree_check_state is very large to put on the stack :-(

I have reverted that commit for today.
