+ * pgtable page can go away from under us! It can be done by a pmd
+ * unshare with a follow up munmap() on the other process), then we
+ * need either:
+ *
+ * (2.1) hugetlb vma lock read or write held, to make sure pmd unshare
+ * won't happen upon the range (it also makes sure the pte_t we
+ * read is the right and stable one), or,
+ *
+ * (2.2) hugetlb mapping i_mmap_rwsem lock held read or write, to make
+ * sure even if unshare happened the racy unmap() will wait until
+ * i_mmap_rwsem is released.
+ *
+ * Option (2.1) is the safest, which guarantees pte stability from pmd
+ * sharing pov, until the vma lock released. Option (2.2) doesn't protect

- * FOLL_PIN and FOLL_LONGTERM may be used in various combinations with each
- * other. Here is what they mean, and how to use them:
- *
- * FOLL_LONGTERM indicates that the page will be held for an indefinite time
- * period _often_ under userspace control. This is in contrast to
- * iov_iter_get_pages(), whose usages are transient.
- *
- * FIXME: For pages which are part of a filesystem, mappings are subject to the
- * lifetime enforced by the filesystem and we need guarantees that longterm
- * users like RDMA and V4L2 only establish mappings which coordinate usage with
- * the filesystem. Ideas for this coordination include revoking the longterm
- * pin, delaying writeback, bounce buffer page writeback, etc. As FS DAX was
- * added after the problem with filesystems was found FS DAX VMAs are
- * specifically failed. Filesystem pages are still subject to bugs and use of
- * FOLL_LONGTERM should be avoided on those pages.
- *
- * FIXME: Also NOTE that FOLL_LONGTERM is not supported in every GUP call.
- * Currently only get_user_pages() and get_user_pages_fast() support this flag
- * and calls to get_user_pages_[un]locked are specifically not allowed. This
- * is due to an incompatibility with the FS DAX check and
- * FAULT_FLAG_ALLOW_RETRY.
- *
- * In the CMA case: long term pins in a CMA region would unnecessarily fragment
- * that region. And so, CMA attempts to migrate the page before pinning, when
- * FOLL_LONGTERM is specified.
- *
- * FOLL_PIN indicates that a special kind of tracking (not just page->_refcount,
- * but an additional pin counting system) will be invoked. This is intended for
- * anything that gets a page reference and then touches page data (for example,
- * Direct IO). This lets the filesystem know that some non-file-system entity is
- * potentially changing the pages' data. In contrast to FOLL_GET (whose pages
- * are released via put_page()), FOLL_PIN pages must be released, ultimately, by
- * a call to unpin_user_page().
- *
- * FOLL_PIN is similar to FOLL_GET: both of these pin pages. They use different
- * and separate refcounting mechanisms, however, and that means that each has
- * its own acquire and release mechanisms:
- *
- * FOLL_GET: get_user_pages*() to acquire, and put_page() to release.
- *
- * FOLL_PIN: pin_user_pages*() to acquire, and unpin_user_pages to release.
- *
- * FOLL_PIN and FOLL_GET are mutually exclusive for a given function call.

+ *
+ *
+ * FIXME: For pages which are part of a filesystem, mappings are subject to the
+ * lifetime enforced by the filesystem and we need guarantees that longterm
+ * users like RDMA and V4L2 only establish mappings which coordinate usage with
+ * the filesystem. Ideas for this coordination include revoking the longterm
+ * pin, delaying writeback, bounce buffer page writeback, etc. As FS DAX was
+ * added after the problem with filesystems was found FS DAX VMAs are
+ * specifically failed. Filesystem pages are still subject to bugs and use of
+ * FOLL_LONGTERM should be avoided on those pages.
+ *
+ * In the CMA case: long term pins in a CMA region would unnecessarily fragment
+ * that region. And so, CMA attempts to migrate the page before pinning, when
+ * FOLL_LONGTERM is specified.
+ *
+ * FOLL_PIN indicates that a special kind of tracking (not just page->_refcount,
+ * but an additional pin counting system) will be invoked. This is intended for
+ * anything that gets a page reference and then touches page data (for example,
+ * Direct IO). This lets the filesystem know that some non-file-system entity is
+ * potentially changing the pages' data. In contrast to FOLL_GET (whose pages
+ * are released via put_page()), FOLL_PIN pages must be released, ultimately, by
+ * a call to unpin_user_page().
+ *
+ * FOLL_PIN is similar to FOLL_GET: both of these pin pages. They use different
+ * and separate refcounting mechanisms, however, and that means that each has
+ * its own acquire and release mechanisms:
+ *
+ * FOLL_GET: get_user_pages*() to acquire, and put_page() to release.
+ *
+ * FOLL_PIN: pin_user_pages*() to acquire, and unpin_user_pages to release.

+ * For each node, memcgs are divided into two generations: the old and the
+ * young. For each generation, memcgs are randomly sharded into multiple bins
+ * to improve scalability. For each bin, the hlist_nulls is virtually divided
+ * into three segments: the head, the tail and the default.
+ *
+ * An onlining memcg is added to the tail of a random bin in the old generation.
+ * The eviction starts at the head of a random bin in the old generation. The
+ * per-node memcg generation counter, whose reminder (mod MEMCG_NR_GENS) indexes
+ * the old generation, is incremented when all its bins become empty.
+ *
+ * There are four operations:
+ * 1. MEMCG_LRU_HEAD, which moves an memcg to the head of a random bin in its
+ * current generation (old or young) and updates its "seg" to "head";
+ * 2. MEMCG_LRU_TAIL, which moves an memcg to the tail of a random bin in its
+ * current generation (old or young) and updates its "seg" to "tail";
+ * 3. MEMCG_LRU_OLD, which moves an memcg to the head of a random bin in the old
+ * generation, updates its "gen" to "old" and resets its "seg" to "default";
+ * 4. MEMCG_LRU_YOUNG, which moves an memcg to the tail of a random bin in the
+ * young generation, updates its "gen" to "young" and resets its "seg" to
+ * "default".
+ *
+ * The events that trigger the above operations are:
+ * 1. Exceeding the soft limit, which triggers MEMCG_LRU_HEAD;
+ * 2. The first attempt to reclaim an memcg below low, which triggers
+ * MEMCG_LRU_TAIL;
+ * 3. The first attempt to reclaim an memcg below reclaimable size threshold,
+ * which triggers MEMCG_LRU_TAIL;
+ * 4. The second attempt to reclaim an memcg below reclaimable size threshold,
+ * which triggers MEMCG_LRU_YOUNG;
+ * 5. Attempting to reclaim an memcg below min, which triggers MEMCG_LRU_YOUNG;
+ * 6. Finishing the aging on the eviction path, which triggers MEMCG_LRU_YOUNG;
+ * 7. Offlining an memcg, which triggers MEMCG_LRU_OLD.
+ *
+ * Note that memcg LRU only applies to global reclaim, and the round-robin
+ * incrementing of their max_seq counters ensures the eventual fairness to all
+ * eligible memcgs. For memcg reclaim, it still relies on mem_cgroup_iter().

- * A generic stack depot implementation

+ *
+ * Stack depot is intended to be used by subsystems that need to store and
+ * later retrieve many potentially duplicated stack traces without wasting
+ * memory.
+ *
+ * For example, KASAN needs to save allocation and free stack traces for each
+ * object. Storing two stack traces per object requires a lot of memory (e.g.
+ * SLUB_DEBUG needs 256 bytes per object for that). Since allocation and free
+ * stack traces often repeat, using stack depot allows to save about 100x space.
+ *
+ * Stack traces are never removed from the stack depot.
