Subject: [GIT PULL] siginfo work for v4.18-rc1
Linus,
Please pull the siginfo-linus branch from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git siginfo-linus
HEAD: 26da35010c6d6ce317d511c8186585bdd8ab6629 signal/sh: Stop gcc warning about an impossible case in do_divide_error
Apologies for the resend I spaced and forgot the diffstat earlier.
This set of changes close the known issues with setting si_code to an
invalid value, and with not fully initializing struct siginfo. There
remains work to do on nds32, arc, unicore32, powerpc, arm, arm64, ia64
and x86 to get the code that generates siginfo into a simpler and more
maintainable state. Most of that work involves refactoring the signal
handling code and thus careful code review.
Also not included is the work to shrink the in kernel version of struct
siginfo. That depends on getting the number of places that directly
manipulate struct siginfo under control, as it requires the introduction
of struct kernel_siginfo for the in kernel things.
Overall this set of changes looks like it is making good progress,
and with a little luck I will be wrapping up the siginfo work
next development cycle.
