Subject[PATCH 4.11 028/197] dm mpath: split and rename activate_path() to prepare for its expanded use
Date
4.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Van Assche <bart.vanassche@sandisk.com>

commit 89bfce763e43fa4897e0d3af6b29ed909df64cfd upstream.

activate_path() is renamed to activate_path_work() which now calls
activate_or_offline_path(). activate_or_offline_path() will be used
by the next commit.
