From 58d926187758f76647d68e2f51ce44e6ace81873 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Tue, 20 Mar 2012 21:26:48 -0700 Subject: target: Remove obsolete DF_READ_ONLY usage This was used at one time as a hack by FILEIO backend registration to allow a struct block_device that was claimed with blkdev_get (by a local filesystem mount for example) to be exported as read-only (SCSI WP=1). Since FILEIO backend registration will no longer attempt to obtain exclusive access to an underlying struct block_device here, this flag is now obsolete.
