This is a note to let you know that I've just added the patch titled
devres: Align data[] to ARCH_KMALLOC_MINALIGNto my driver-core git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git in the driver-core-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

Initially we bumped into problem with 32-bit aligned atomic64_t on ARC, see [1]. And then during quite lengthly discussion Peter Z. mentioned ARCH_KMALLOC_MINALIGN which IMHO makes perfect sense. If allocation is done by plain kmalloc() obtained buffer will be ARCH_KMALLOC_MINALIGN aligned and then why buffer obtained via devm_kmalloc() should have any other alignment?

I noticed this patch was not only merged in Linus' tree quite some time ago but it was as well back-ported to v4.20, see [1] but for some reason there's no backport to either LTS kernel (v4.19, v4.14 and v4.9).
Is there any problem with this patch and LTS kernels or may we have this one applied?
