Hi all,

After merging the block tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

net/sunrpc/xprtsock.c: In function 'xs_flush_bvec':
net/sunrpc/xprtsock.c:390:2: error: implicit declaration of function 'for_each_bvec'; did you mean 'for_each_net'? [-Werror=implicit-function-declaration]
  for_each_bvec(bv, bvec, bi, bi)
  ^~~~~~~~~~~~~
  for_each_net
net/sunrpc/xprtsock.c:390:33: error: expected ';' before 'flush_dcache_page'
  for_each_bvec(bv, bvec, bi, bi)
                                 ^
                                 ;
   flush_dcache_page(bv.bv_page);
   ~~~~~~~~~~~~~~~~~              

Caused by commit

  f3effe4c1240 ("block: rename bvec helpers")

interacting with commit

  6a829eb8619f ("SUNRPC: Fix TCP receive code on archs with flush_dcache_page()")

from the nfs-anna tree.

[I love API changes :-(]

I have applied the following merge fix patch:

This fix is correct, thanks!

Thanks,
