The patch titled Subject: aoe: allow user to disable target failure timeout has been removed from the -mm tree. Its filename was aoe-allow-user-to-disable-target-failure-timeout.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Ed Cashin <ecashin@xxxxxxxxxx> Subject: aoe: allow user to disable target failure timeout With this change, the aoe driver treats the value zero as special for the aoe_deadsecs module parameter. Normally, this value specifies the number of seconds during which the driver will continue to attempt retransmits to an unresponsive AoE target. After aoe_deadsecs has elapsed, the aoe driver marks the aoe device as "down" and fails all I/O. The new meaning of an aoe_deadsecs of zero is for the driver to retransmit commands indefinitely.
