It\u0027s the missing\n piece he needed for both btrfs send/receive and subvolume quotas.\n Neither of those are ready yet, but the new tracking code is included\n here. Most of the time, the new code is off. It is only used by\n scrub and other backref walkers.\n\n Stefan Behrens has added io failure tracking.

In the criu\n(checkpoint/restore) project we dump the tasks\u0027 memory into image files\nand to do it properly we need to detect which pages inside mappings are\nreally in use. The mincore syscall I though could help with this did not.\n First, it doesn\u0027t report swapped pages, thus we cannot find out which\nparts of anonymous mappings to dump. Next, it does report pages from page\ncache as present even if they are not mapped, and it doesn\u0027t make that has\nnot been cow-ed.\n\nNote, that issue with swap pages is critical -- we must dump swap pages to\nimage file. But the issues with file pages are optimization -- we can\ntake all file pages to image, this would be correct, but if we know that a\npage is not mapped or not cow-ed, we can remove them from dump file. The\ndump would still be self-consistent, though significantly smaller in size\n(up to 10 times smaller on real apps).\n\nAndrew noticed, that the proc pagemap file solved 2 of 3 above issues --\nit reports whether a page is present or swapped and it doesn\u0027t report not\nmapped page cache pages.
