I have some comments. See below.

I do not like this. Even with this variable, some part of buffer may be
spuriously fontified. Maybe you just verify that you are at actual
inline-src block by examining org-element-context?

org-fontify-inline-src-results is not defined in this patch.

Is there some special reason why you apply both 'shadow and
'org-inline-src-block? What about 'org-meta-line face? Maybe
'org-meta-line should not be hard-coded?

It looks like you are repeating the job of org-element-context here. Why
don't you just get the proper object?

Do you really intend to use 'org-block and 'shadow faces here? Not
'org-inline-src-block?

Looks like a stray defcustom. At least, it is not mentioned in the
commit message and not used within the patch.

Best,
