Subject: Re: [RFCv3 00/21] TCM Core and TCM_Loop patches for v2.6.37


Some comments on the configfs to backend API:

 - the various get_*_info methods look like they really should use
   the seq_file API.  That gives you safety against overflows,
   and simplifies the code.
 - why are show_configfs_dev_params and get_dev_info separate
   methods if they always end up calling the same code?
 - the set_configfs_dev_params method implementation contains some
   rather nast parsing code.  They look like they really should use
   the parser.h helpers we use for mount option parsing.
