FYI:
And, from your test log, it looks like you were running an old LTP
version, the test#2 was added in move_page12 in the latest master
branch.
So, the completely test log should be included two-part:
# ./move_pages12
tst_test.c:1100: INFO: Timeout per run is 0h 05m 00s
move_pages12.c:252: INFO: Free RAM 63759028 kB
move_pages12.c:270: INFO: Increasing 2048kB hugepages pool on node 0 to 4
move_pages12.c:280: INFO: Increasing 2048kB hugepages pool on node 1 to 6
move_pages12.c:196: INFO: Allocating and freeing 4 hugepages on node 0
move_pages12.c:196: INFO: Allocating and freeing 4 hugepages on node 1
move_pages12.c:186: PASS: Bug not reproduced
move_pages12.c:186: PASS: Bug not reproduced
Summary:
passed 2
failed 0
skipped 0
warnings 0
