The proper commit quotation format is done by adding this to your
.gitconfig:

[core]
        abbrev = 12
[alias]
        one = show -s --pretty='format:%h (\"%s\")'

and then doing:

$ git one <commit id>

which will give you

0e4c12b45aa8 ("x86/mm, resource: Use PAGE_KERNEL protection for ioremap of memory pages")

Well, it is not really checking that.

What confusion?

The justification for that change sounds really fishy.

Good mailing practices for 400: avoid top-posting and trim the reply.
