Previously, the submission flow works with cached compressed pages reclaim path in a tricky way, and it could be buggy if the reclaim path changes later without such tricky restrictions. For example, currently one PagePrivate(page) is evaluated without taking page lock (it only follows a wait_for_page_locked which closes such race) and no handling solves the potential page truncation case. In addition, it's also full of #ifdefs in the function, which is hard to understand and maintain. this patch fixes them all.
