Rafael J. Wysocki 968808b895 [PATCH] swsusp: use less memory during resume Make swsusp allocate only as much memory as needed to store the image data and metadata during resume. Without this patch swsusp additionally allocates many page frames that will conflict with the "original" locations of the image data and are considered as "unsafe", treating them as "eaten" pages (ie. allocated but unusable). The patch makes swsusp allocate as many pages as it'll need to store the data read from the image in one shot, creating a list of allocated "safe" pages, and use the observation that all pages allocated by it are marked with the PG_nosave and PG_nosave_free flags set. Namely, when it's about to load an image page, swsusp can check whether the page frame corresponding to the "original" location of this page has been allocated (ie. if the page frame has the PG_nosave and PG_nosave_free flags set) and if so, it can load the page directly into this page frame. Otherwise it uses an allocated "safe" page from the list to store the data that will be copied to their "original" location later on. This allows us to save many page copyings and page allocations during resume and in the future it may allow us to load images greater than 50% of the normal zone. Signed-off-by: Rafael J.
