Hi all,

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

drivers/dma/uniphier-xdmac.c: In function 'uniphier_xdmac_prep_dma_memcpy':

Caused by commit

  f0187db056dc ("iov_iter: Move unnecessary inclusion of crypto/hash.h")

I have reverted that commit for today.
