So far most of the concerns have been around usage of kernfs_rwsem and those can be addressed independent of first 5 (even first 7 )changes here. Just one question in this regard, should I send the new patch set (addressing open_file_mutex and list conversion) as a separate patch set or should I sent it as v9 of ongoing change set. I guess first option is better but thought of confirming once before proceeding. Thanks -- Imran > Thanks. >
