Michal, you are right.

$ git merge-base 7e8f54cd  630f289
7e8f54cd4e2628fada942fe9ba1fc46e99e94218


630f289 has 7e8f54cd
as an ancestor.


You did not do anything wrong.
Me neither.
Both sides submitted correct patches.


One unfortunate thing occurred
when 630f289 got in via akpm tree.

Andrew Morton manages patches by
quilt instead of git.

He rebases patches before sending them to
Linus in the MW, but does not check the
rebased result.


You can replace the tag with:

Fixes: 630f289b7114 ("asm-generic: make more kernel-space headers mandatory")
