Subject: test/skodic: make a bit more portable
X-Git-Tag: v4.8~67
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=5cf23c53b8a96269ef72b6d675c811c8132ae5ec;p=strace

test/skodic: make a bit more portable

* test/skodic.c (main): Don't use MAP_FIXED since valid virtual addresses
vary between architectures (as far as I can tell the use of MAP_FIXED is
not relevant to the test).  Also don't assume the file desriptor returned
by open call is 3 when passing it to mmap.
