Please stick with the git coding style, see
Documentation/CodingGuidelines.
It's forgivable to "fix style while at it" to some extent, but in this
case it's both moving away from our normal style (by indenting case
labels), and in doing so making the diff larger/worse.
This should be a one-line addition of your new EACCES case.
I haven't read through the rest yet, but please self-review those
patches with a keen eye to diff size & seeing if there's similar
issues. E.g. are they the same lines changed under "git show -w", if not
are you sure you're correct in making the style change?

I see this is changing the ESOMETHINGELSE added in your 3/6, if you make
this patch come first then presumably we won't have that churn.
And if we don't have a test that's relying on ESOMETHINGELSE (maybe we
do, but don't test_cmp it, I haven't checked) shouldn't this "default"
case just be:
BUG("unknown errno %d: %s", errno_number, strerror(errno_number))
I.e. if we have OK coverage here we'd presumably fail the test case
itself anyway, so shouldn't we fail here too?
