[lustre-devel] [PATCH 09/27] lustre: llite: refresh layout after mirror merge/split

[James Simmons]

From: Bobi Jam <bobijam at whamcloud.com>

mirror merge/split updates file's LOVEA and revokes client's layout
lock, but the client issuing the layout change needs to refresh its
layout (lov->lsm) as well.
