Changes in v2:
get_allowed_pages()
- removed tst_resm(TFAIL,..)
- added break
- for ret == -3, set errno to EINVAL
move_pages_support.c
- check return value from get_allowed_nodes_arr()
mbind, get_mempolicy, move_pages
- removed curly brackets in single statement ifs
This patch series is a combination of:
[PATCH v3] mbind01, get_mempolicy01: dont use hardcoded node 0
[PATCH 1/2] move_pages_support: use only allowed nodes
[PATCH 2/2] move_pages: dont use hardcoded node numbers
so that all testcases use same shared code, which resides in libnuma_helper.a.
This library defines get_allowed_nodes() and get_allowed_nodes_arr() functions
to obtain list of nodes tests can use.
I tested it with following setups. Note that setup 4 and 5 will
end with TCONF as there is only 1 node with memory.
1.

Hi Jan,
you sent many series of patches, but it's hard to find out that
which patch belongs to this series.
So, can you send patch set like this.
[0]-xxxxxxxxxxxxxxxxxxxxxxx
|_[1]xxxxxxxxxxxxxxxxxxxxxxxxx
|_[2]xxxxxxxxxxxxxxxxxxxxxxxx
I mean, one series in one thread ?
Thanks,
Wanlong Gao

My apologies, I kept merging them together as same pattern
was repeating in different syscall testcases.

Sure, I'll resend (once I check that my client does the right thing).

Live Security Virtual Conference
Exclusive live event will cover all the ways today's security and
threat landscape has changed and how IT managers can respond. Discussions
will include endpoint security, mobile security and the latest in malware
threats. http://www.accelacomm.com/jaw/sfrnl04242012/114/50122263/

* [LTP] [PATCH v2 0/4] dont use hardcoded NUMA node ids

Changes in v2:
get_allowed_pages()
- removed tst_resm(TFAIL,..)
- added break
- for ret == -3, set errno to EINVAL
move_pages_support.c
- check return value from get_allowed_nodes_arr()
mbind, get_mempolicy, move_pages
- removed curly brackets in single statement ifs
This patch series is a combination of:
[PATCH v3] mbind01, get_mempolicy01: dont use hardcoded node 0
[PATCH 1/2] move_pages_support: use only allowed nodes
[PATCH 2/2] move_pages: dont use hardcoded node numbers
so that all testcases use same shared code, which resides in libnuma_helper.a.
This library defines get_allowed_nodes() and get_allowed_nodes_arr() functions
to obtain list of nodes tests can use.
I tested it with following setups. Note that setup 4 and 5 will
end with TCONF as there is only 1 node with memory.
