Subject: [PATCH] [Target_Core_Mod/ConfigFS]: Added CONFIGFS_SYSFS_SYMLINKS support
Date: Fri, 17 Oct 2008 00:02:37 -0700 [thread overview]
Message-ID: <1224226957.5556.287.camel@haakon2.linux-iscsi.org> (raw)
[-- Attachment #1: Type: text/plain, Size: 1836 bytes --]
Added allow_link_kobject() and drop_link_kobject() calls to
/sys/kernel/config/target/core/$HBA_$ID/$STORAGE_OBJECT
Then means the following code now works for accessing struct block_device
and struct scsi_device through Linux/BLOCK and Linux/SCSI subsystems
respectively.
export TARGET=/sys/kernel/config/target/core/
export FABRIC=/sys/kernel/config/target/iscsi/
mkdir -p $TARGET/iblock_0/lvm_test0
ln -s /sys/block/dm-2 $TARGET/iblock_0/lvm_test0/dm-2
mkdir -p $TARGET/pscsi_0/sdd
ln -s /sys/block/sdd/device $TARGET/pscsi_0/sdd/passthrough
export DEF_IQN="iqn.2003-01.org.linux-iscsi.target.i686:sn.e475ed6fcdd0"
<SNIP..>
mkdir -p "$FABRIC/$DEF_IQN/tpgt_1/lun/lun_0"
ln -s $TARGET/iblock_0/lvm_test0 "$FABRIC/$DEF_IQN/tpgt_1/lun/lun_0/lio_west_port"
mkdir -p "$FABRIC/$DEF_IQN/tpgt_1/lun/lun_1"
ln -s $TARGET/pscsi_0/sdd "$FABRIC/$DEF_IQN/tpgt_1/lun/lun_1/lio_east_port"
