Description Florian Weimer 2018-10-25 09:26:51 UTC 
The kernel uses int, not long int.  For 32-bit, we can keep using long int, but we need to XFAIL the int type for si_band for sparc64.

    conform: XFAIL siginfo_t si_band test on sparc64

For glibc 2.26, the conform tests are still globally XFAIL'd, so I did not backport anything there.

Of course, this does not address the type mismatch.  Given this concerns an obsolete STREAMS feature and siginfo_t is very hard to rewrite, changing the exposed type from int to long int on sparc64 appears to be wasted effort.
