i think it's incorrect in its current form, because 'pos' is not necessarily safe and might be removed from the commit_list?
the whole loop could be a "while (!list_empty(head))" thing, if it wasnt for the possibility for an nfs_set_page_writeback_locked() to skip an entry. Maybe a local list of 'already processed' requests should be built, and once the main list is emptied, moved back into the main list? Then the lock-break could be moved to the end of the loop.
