From 9ad5204d68a3b48b92907d88d1c28d33fde6ba2a Mon Sep 17 00:00:00 2001 From: "Salyzyn, Mark" Date: Tue, 17 Jul 2007 11:15:08 -0400 Subject: [PATCH] [SCSI] aacraid: incorrect dma mapping mask during blinkled recover or user initiated reset Incorrect dma mask was used for blinkled (firmware assert) recovery or user initiated reset during initialization portion. Ensure that all callers of aac_fib_map_free null out the fib allocation references to prevent multiple free. Although serious sounding, no reports of these problems have surfaced...
