Subject: linux-next: manual merge of the notifications tree with the vfs
 tree

Hi all,

Today's linux-next merge of the notifications tree got conflicts in:

  arch/alpha/kernel/syscalls/syscall.tbl
  arch/arm/tools/syscall.tbl
  arch/arm64/include/asm/unistd.h
  arch/arm64/include/asm/unistd32.h
  arch/ia64/kernel/syscalls/syscall.tbl
  arch/m68k/kernel/syscalls/syscall.tbl
  arch/microblaze/kernel/syscalls/syscall.tbl
  arch/mips/kernel/syscalls/syscall_n32.tbl
  arch/mips/kernel/syscalls/syscall_n64.tbl
  arch/mips/kernel/syscalls/syscall_o32.tbl
  arch/parisc/kernel/syscalls/syscall.tbl
  arch/powerpc/kernel/syscalls/syscall.tbl
  arch/s390/kernel/syscalls/syscall.tbl
  arch/sh/kernel/syscalls/syscall.tbl
  arch/sparc/kernel/syscalls/syscall.tbl
  arch/x86/entry/syscalls/syscall_32.tbl
  arch/x86/entry/syscalls/syscall_64.tbl
  arch/xtensa/kernel/syscalls/syscall.tbl
  include/uapi/asm-generic/unistd.h

between commit:

  c8ffd8bcdd28 ("vfs: add faccessat2 syscall")

from the vfs tree and commits:

  cd7109637b0b ("watch_queue: Implement mount topology and attribute change notifications")
  46896d79c514 ("watch_queue: Add superblock notifications")

from the notifications tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

-- 
Cheers,
Stephen Rothwell
