Hi all,

After merging the device-mapper tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

/home/sfr/next/next/drivers/md/dm-table.c: In function 'dm_table_set_restrictions':
/home/sfr/next/next/drivers/md/dm-table.c:1899:3: error: implicit declaration of function 'queue_flag_set_unlocked'; did you mean 'lookup_one_len_unlocked'? [-Werror=implicit-function-declaration]
   queue_flag_set_unlocked(QUEUE_FLAG_SECERASE, q);
   ^~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  9723d9db1a84 ("dm: add support for secure erase forwarding")

interacting with commit

  8a0ac14b8da9 ("block: Move the queue_flag_*() functions from a public into a private header file")

from the block tree.

I have added the following merge fix patch:
