This is likely to be a libps problem. + +Improvements and new features +----------------------------- + +* There is a lot of dynamic memory allocation going on and it comes with a + cost in performance. We could try to limit such allocation, as long as it + keeps the inner interface simple and preserves the read/readdir semantics + (performance is probably not critical for a proc filesystem.) + One way would be to add an (optional) "needed_length" field to + procfs_node_ops, and arrange to pass a sufficent buffer in (*contents, + *contents_len) when get_contents is called. Then the user-provided buffer + might be used directly under some circumstances. + +* Add thread directories as [pid]/task/[n]. This shouldn't be too hard if we + use "process" nodes for threads, and provide an "exists" hook for the "task" + entry itself so that it's disabled in thread nodes. It might prove necessary + to have "optional" libps flags for some content generators, though, since + some of them might be missing for threads. + |
