Cashin Date: Wed, 20 Sep 2006 18:36:50 +0000 (-0400) Subject: aoe: module parameter for device timeout X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b751e8b6590efdb76e1682c85bfcd5f3531ccae4;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git aoe: module parameter for device timeout The aoe_deadsecs module parameter sets the number of seconds that elapse before a nonresponsive AoE device is marked as dead. This is runtime settable in sysfs or settable with a module load or kernel boot parameter. Signed-off-by: "Ed L.
