Hi all,

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

drivers/md/dm-vdo/io-factory.c: In function 'read_ahead':
drivers/md/dm-vdo/io-factory.c:118:17: error: too few arguments to function=
 'dm_bufio_prefetch'
  118 |                 dm_bufio_prefetch(reader->client, block_number, rea=
d_ahead);

Caused by commit

  82da73bac1ee ("dm vdo: add deduplication index storage interface")

interacting with commit

  3be93545346e ("dm bufio: Support IO priority")

I have used the device-mapper tree from next-20240206 for today.
