selftests/mm: pass filename as input param to VM_PFNMAP tests
Enable these tests to be run on other pfnmap'ed memory like NVIDIA's EGM.
Add '--' as a separator to pass in file path. This allows passing of cmd
line arguments to kselftest_harness. Use '/dev/mem' as default filename.
Existing test passes:
pfnmap
TAP version 13
1..6
# Starting 6 tests from 1 test cases.
# PASSED: 6 / 6 tests passed.
# Totals: pass:6 fail:0 xfail:0 xpass:0 skip:0 error:0
Pass params to kselftest_harness:
pfnmap -r pfnmap:mremap_fixed
TAP version 13
1..1
# Starting 1 tests from 1 test cases.
# RUN pfnmap.mremap_fixed ...
# OK pfnmap.mremap_fixed
ok 1 pfnmap.mremap_fixed
# PASSED: 1 / 1 tests passed.
# Totals: pass:1 fail:0 xfail:0 xpass:0 skip:0 error:0
Pass non-existent file name as input:
pfnmap -- /dev/blah
TAP version 13
1..6
# Starting 6 tests from 1 test cases.
# RUN pfnmap.madvise_disallowed ...
# SKIP Cannot open '/dev/blah'
Pass non pfnmap'ed file as input:
pfnmap -r pfnmap.madvise_disallowed -- randfile.txt
TAP version 13
1..1
# Starting 1 tests from 1 test cases.
# RUN pfnmap.madvise_disallowed ...
# SKIP Invalid file: 'randfile.txt'. Not pfnmap'ed
