The idea is interesting for me :) Anyway, I think proc_pid_##FIELD
could be made as static inline, and instead of putting "switch" into
it, maybe you can split it as proc_pid_##FIELD_{read,write}. Thus the
function is smaller and the code path can be made faster (no branch,
no call)
BTW, isn't "page" in proc_tasklv_read() should be written as" struct
page *page" instead?
Also, get_proc_task should be put after __get_free_pages, thus if
somehow the functions must sleep, it does so without holding
task_struct's lock. Don't you guys agree?
That's all so far, I hope my suggestion is useful...
regards,
Mulyadi.
