SubjectRe: [PATCH] linux/export.h: remove unneeded .balign directive
Happy new 2024 Masahiro,

some small nits.

What about adding links to the commits...

linux/export: Fix alignment for 64-bit ksymtab entries
[ Upstream commit f6847807c22f6944c71c981b630b9fff30801e73 ]

linux/export: Ensure natural alignment of kcrctab array
[ Upstream commit 753547de0daecbdbd1af3618987ddade325d9aaa ]

^^ AFAICS in linux-stable - v6.6.10-rc1 includes both
^^ Is yours a follow-up and makes sense for linux-stable releases?

...and CC Helge Deller?

Best regards,
-Sedat-
