linux-next: manual merge of the pidfd tree with the m68k, vfs and keys trees

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

Today's linux-next merge of the pidfd 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/linux/syscalls.h
  include/uapi/asm-generic/unistd.h

between commits:

  e8bb2a2a1d51 ("m68k: Wire up clone3() syscall")
  0a51692d49ec ("open: introduce openat2(2) syscall")
  3a92c6e49c47 ("Add a general, global device notification watch list")

from the m68k, vfs and keys trees and commit:

  27063d9f5fbf ("arch: wire up pidfd_getfd syscall")

from the pidfd 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
