Subject: [GIT PULL] livepatching for 5.1
Linus,
please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/livepatching/livepatching.git for-linus
to receive livepatching subsystem updates for 5.1 merge window:
=====
- support for something we call 'atomic replace', and allows for much
better handling of cumulative patches (which is something very useful
for distros), from Jason Baron with help of Petr Mladek and Jason Baron.
- improvement of handling of tasks blocking finalization, from Miroslav
Benes
- update of MAINTAINERS file to reflect move towards group maintainership
=====
Thanks.
