Subject: Will the recent memory leak fixes be backported to longterm kernels?

Hi all,
When debugging a memory leak issue (https://github.com/coreos/bugs/issues/2516)
with v4.14.11-coreos, we noticed the same issue may have been fixed recently by
Roman in the latest mainline (i.e. Linus's master branch) according to comment #7 of 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1792349, which lists these
patches (I'm not sure if the 5-patch list is complete):

010cb21d4ede math64: prevent double calculation of DIV64_U64_ROUND_UP() arguments
f77d7a05670d mm: don't miss the last page because of round-off error
d18bf0af683e mm: drain memcg stocks on css offlining
71cd51b2e1ca mm: rework memcg kernel stack accounting
f3a2fccbce15 mm: slowly shrink slabs with a relatively small number of objects

Obviously at least some of the fixes are also needed in the longterm kernels like v4.14.y,
but none of the 5 patches has the "Cc: stable@...r.kernel.org" tag? I'm wondering if
these patches will be backported to the longterm kernels. BTW, the patches are not
in v4.19, but I suppose they will be in v4.19.1-rc1?

Thanks,
