Hence we cant expect the resulting bitmap to have a higher value than what it was earlier. cc: Dave Hansen cc: Florian Weimer Signed-off-by: Ram Pai --- tools/testing/selftests/vm/protection_keys.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/tools/testing/selftests/vm/protection_keys.c b/tools/testing/selftests/vm/protection_keys.c index 83216c5..0109388 100644 --- a/tools/testing/selftests/vm/protection_keys.c +++ b/tools/testing/selftests/vm/protection_keys.c @@ -443,7 +443,7 @@ void pkey_disable_set(int pkey, int flags) dprintf1("%s(%d) pkey_reg: 0x%lx\n", __func__, pkey, rdpkey_reg()); if (flags) - pkey_assert(rdpkey_reg() > orig_pkey_reg); + pkey_assert(rdpkey_reg() >= orig_pkey_reg); dprintf1("END<---%s(%d, 0x%x)\n", __func__, pkey, flags); } -- 1.7.1
