Subject[PATCH 3.12 151/181] Target/iser: Wait for proper cleanup before unloading
Date
From: Sagi Grimberg <sagig@mellanox.com>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit f5ebec9629cf78eeeea4b8258882a9f439ab2404 upstream.

disconnected_handler works are scheduled on system_wq.
When attempting to unload, first make sure all works
have cleaned up.
