Hi all,
After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:
drivers/md/dm-cache-policy-cleaner.c: In function 'alloc_hash':
drivers/md/dm-cache-policy-cleaner.c:87:2: error: implicit declaration of function 'vzalloc' [-Werror=implicit-function-declaration]

Caused by commits d5d224ab22e4 ("Add a target that allows a fast device
such as an SSD to be used as a"), b5dc50616996 ("A cache policy that uses
a multiqueue ordered by recent hit") and 9c44464a0aed ("A simple cache
policy that writes back all data to the origin") from the device-mapper
tree.
I added the following fix patch for today:
