Make sure that the commit bcache: Fix __bch_btree_node_alloc to make the failure behavior consistent is committed _before_ this "Remove some unnecessary NULL point check..." patch.
Oh, sorry for my mistake. I forgot to commit the first patch. I'll try to commit it first.
It would be a good idea to add "this patch depends on `bcache: Fix __bch_btree_node_alloc to make the failure behavior consistent`" to the commit message so the stable maintainers know.
Yes, I will append that msg in the next version.
Best regargds, Zheng
