[LTP] [PATCH 1/1] cacheflush01: Rewrite into new API
Petr Vorel

Fri Oct 2 22:24:16 CEST 2020
This syscall is currently (v5.9) supported on these architectures:
arc, csky, mips, m68k, nds32, sh
constants are missing for m68k, not sure if the testcase is valid for it.
Untested.
Test for __LTP__NR_INVALID_SYSCALL saves adding autotools check for
<asm/cachectl.h>.

Hi,
FYI: I was going to ask for removal of this test, but all these archs are
still supported. This test compiles on all archs now, but I haven't run
it (I don't have access to none of these archs, not sure if LTP is even
tested on these archs).
Kind regards,
Petr
