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.

Hi Jens,

Thanks, I'll drop it. It's not part of the initial request sent to
Linus, exactly because it arrived late.

Coly, I'm dropping this series.

Yes please. Should I re-submit the fixed series to you in later -RC round, or wait for 5.20 merge window?


Thanks.

Coly Li
