[lustre-devel] [PATCH 073/622] lustre: hsm: add OBD_CONNECT2_ARCHIVE_ID_ARRAY to pass archive_id lists in array

[James Simmons]

From: Teddy Zheng <teddy at ddn.com>

Clients registed to MDS with OBD_CONNECT2_ARCHIVE_ID_ARRAY will
use array to pass ARCHIVED IDs. While clients without it still
use bitmap. This flag allows old clients connect to new MDSs.
