While working on commitb5372fe5dc("exec: load_script: Do not exec truncated interpreter path"), I wrote a series of test scripts to verify corner cases. However, soon after, commit6eb3c3d0a5("exec: increase BINPRM_BUF_SIZE to 256") landed, resulting in the tests needing to be refactored for the larger BINPRM_BUF_SIZE, which got lost on my TODO list. During the recent exec refactoring work[1], the need for these tests resurfaced, so I've finished them up for addition to the kernel selftests.
