From 89f8b33ca1ea881d1d84542282cb85d07d02e78d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 13 Mar 2014 09:38:42 -0600 Subject: block: remove old blk_iopoll_enabled variable This was a debugging measure to toggle enabled/disabled when testing. But for real production setups, it's not safe to toggle this setting without either reloading drivers of quiescing IO first. Neither of which the toggle enforces. Additionally, it makes drivers deal with the conditional state. Remove it completely. It's up to the driver whether iopoll is enabled or not.
