From d0076f7754dce07c7a1d752034561acadd99eafa Mon Sep 17 00:00:00 2001 From: Martin Peschke Date: Thu, 15 Nov 2007 13:57:08 +0100 Subject: [PATCH] [SCSI] zfcp: fix dismissal of error recovery actions zfcp_erp_action_dismiss() used to ignore any actions in the ready list. This is a bug. Any action superseded by a stronger action needs to be dismissed. This patch changes zfcp_erp_action_dismiss() so that it dismisses actions regardless of their list affiliation. The ERP thread is able to handle this. It is important to kick the erp thread only for actions in the running list, though, as an imbalance of wakeup signals would confuse the erp thread otherwise.
