From b95be99d52ce4f9db9ff0bd5f10e9e2066da6d2e Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Thu, 15 Sep 2005 13:52:51 -0400 Subject: [PATCH] [SCSI] fix oops in scsi_release_buffers() I found one other thing that needs to be fixed. The call to scsi_release_buffers in scsi_unprep_request causes an oops, because the sgtable has already been freed in scsi_io_completion. The following patch is needed.
