Subject: linux-next: manual merge of the akpm tree with the security tree
Hi all,
FIXME: Add owner of second tree to To:
Add author(s)/SOB of conflicting commits.
Today's linux-next merge of the akpm tree got conflicts in:
arch/x86/entry/syscalls/syscall_32.tbl
arch/x86/entry/syscalls/syscall_64.tbl
include/linux/syscalls.h
include/uapi/asm-generic/unistd.h
between commit:
c5eafae25eb5 ("landlock: Add syscall implementations")
from the security tree and patch:
"arch, mm: wire up memfd_secret system call where relevant"
from the akpm 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
