------------------------------------------------------ From: Ayush Jain ayush.jain3@amd.com Subject: selftests/mm: FOLL_LONGTERM need to be updated to 0x100 Date: Tue, 8 Aug 2023 07:43:47 -0500
After commit 2c2241081f7d ("mm/gup: move private gup FOLL_ flags to internal.h") FOLL_LONGTERM flag value got updated from 0x10000 to 0x100 at include/linux/mm_types.h.
As hmm.hmm_device_private.hmm_gup_test uses FOLL_LONGTERM Updating same here as well.
Before this change test goes in an infinite assert loop in hmm.hmm_device_private.hmm_gup_test ========================================================== RUN hmm.hmm_device_private.hmm_gup_test ... hmm-tests.c:1962:hmm_gup_test:Expected HMM_DMIRROR_PROT_WRITE.. ..(2) == m[2] (34) hmm-tests.c:157:hmm_gup_test:Expected ret (-1) == 0 (0) hmm-tests.c:157:hmm_gup_test:Expected ret (-1) == 0 (0) ... ==========================================================
