Hi Joel, Greg and Co, Here is the the first working code for allowing configfs to handle symlinks from sysfs struct kobject based code. Here is the commit: passing struct kobject into generic target_core_mod subsystem plugins for locating struct block_device and struct scsi_device.. ------------------------------------------------------------------------- In struct configfs_item_operations, added allow_link_kobject() and drop_link_kobject() to allow struct kobject to be passed through the configfs API. The code for kobject symlink source sits along side the exist configfs symlink code, and does not break existing apps that use allow_link() or drop_link(). Also, there is two large FIXMEs with the first commit, in fs/configfs/symlink.c:configfs_symlink() related to comparing struct nameidata nd.path.dentry->d_sb == sysfs_sb. The 2nd is when doing a 'ls -la' inside of the config group directory containg the symlink source from sysfs, the source link does not currently appear.. I will be following up these two items..

I will send along my patch to drivers/lio-core/target_core_configfs.c in a moment to demonstrate how to pull it all together with struct config_item_operations allow_link_kobject() and drop_link_kobject()..
