> LTP helper functions, mainly safe syscalls, often report two different source
> code locations in error messages and sometimes handle syscall return values
> incorrectly. This patchset unifies source code location formatting to only
> show the calling line in the test program and fixes invalid return value
> handling. Safe syscalls now make pedantic distinction between common errors
> and invalid return values where applicable.
>
> Some safe syscalls returned no value so they were not usable in test cleanup.
> This is also fixed along with potential control flow issues when tst_brk()
> does not immediately terminate the program.
