linux-next: manual merge of the random tree with the vfs-brauner, ftrace trees
Posted by Stephen Rothwell 1 year, 5 months ago 
Hi all,

Today's linux-next merge of the random 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/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 commits:

  e6873349f700 ("fs/xattr: add *at family syscalls")
  190fec72df4a ("uprobe: Wire up uretprobe system call")

from the vfs-brauner, ftrace trees and commit:

  4549ad25b76f ("arch: allocate vgetrandom_alloc() syscall number")

from the random 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,

Wondering why 467 was skipped.

Also, any chance you can let me keep 463 and shift the others (unless
Christian objects)? Or does it not really matter anyway because Linus
is gonna merge this how he wants, separately from what you do in
-next?

It is being used by the uretprobe system call on x86 and asm-generic.

Well, the other new syscalls have been in -next for some time, so I
don't really want to move them (and it would make more work for me :-)).

As you say, Linus will just merge these depending on his own ordering.
However, if you switch to 468/568, then he will probably not change it.
I was also hoping that the uretprobe syscall would change to 467 for
the same reason.
