[LTP] [PATCH 0/2] Change return type of tst_syscall

[Teo Couprie Diaz]

Hello LTP maintainers,

The goal of this patch is to fix a mismatch between the return type used in `tst_syscall`, `int`, and the one used by some syscalls, `long` or `void *` for example, which can be larger than an int and lead to an incorrect test.

As Cyril Hrubis' feedback on the RFC I sent earlier was mostly positive, I am now sending it as a patch proper. Thanks again for having a look !

The main change since the RFC is that the test suite I used for testing the change, specific to test that use tst_syscall, is now in a spearate commit which is not to be merged.
The point is to provide a reference to what was tested and what could be impacted.

Thank you in advance,
