+ * bytes are shown in this abbreviated form (base64-encoded) rather than as the
+ * full ciphertext (base64-encoded). This is necessary to allow supporting
+ * filenames up to NAME_MAX bytes, since base64 encoding expands the length.
+ *
+ * To make it possible for filesystems to still find the correct directory entry
+ * despite not knowing the full on-disk name, we encode any filesystem-specific
+ * 'hash' and/or 'minor_hash' which the filesystem may need for its lookups,
+ * followed by the second-to-last ciphertext block of the filename. Due to the
+ * use of the CBC-CTS encryption mode, the second-to-last ciphertext block
+ * depends on the full plaintext. (Note that ciphertext stealing causes the
+ * last two blocks to appear "flipped".) This makes accidental collisions very
+ * unlikely: just a 1 in 2^128 chance for two filenames to collide even if they
+ * share the same filesystem-specific hashes.
+ *
+ * However, this scheme isn't immune to intentional collisions, which can be
+ * created by anyone able to create arbitrary plaintext filenames and view them
+ * without the key. Making the "digest" be a real cryptographic hash like
+ * SHA-256 over the full ciphertext would prevent this, although it would be
+ * less efficient and harder to implement, especially since the filesystem would
+ * need to calculate it for each directory entry examined during a search.

- * fscrypt_digested_name - alternate identifier for an on-disk filename
- *
- * When userspace lists an encrypted directory without access to the key,
- * filenames whose ciphertext is longer than FSCRYPT_FNAME_MAX_UNDIGESTED_SIZE
- * bytes are shown in this abbreviated form (base64-encoded) rather than as the
- * full ciphertext (base64-encoded). This is necessary to allow supporting
- * filenames up to NAME_MAX bytes, since base64 encoding expands the length.
- *
- * To make it possible for filesystems to still find the correct directory entry
- * despite not knowing the full on-disk name, we encode any filesystem-specific
- * 'hash' and/or 'minor_hash' which the filesystem may need for its lookups,
- * followed by the second-to-last ciphertext block of the filename. Due to the
- * use of the CBC-CTS encryption mode, the second-to-last ciphertext block
- * depends on the full plaintext. (Note that ciphertext stealing causes the
- * last two blocks to appear "flipped".) This makes accidental collisions very
- * unlikely: just a 1 in 2^128 chance for two filenames to collide even if they
- * share the same filesystem-specific hashes.
- *
- * However, this scheme isn't immune to intentional collisions, which can be
- * created by anyone able to create arbitrary plaintext filenames and view them
- * without the key. Making the "digest" be a real cryptographic hash like
- * SHA-256 over the full ciphertext would prevent this, although it would be
- * less efficient and harder to implement, especially since the filesystem would
- * need to calculate it for each directory entry examined during a search.

+ * DOC: Generic radix trees/sparse arrays:
+ *
+ * Very simple and minimalistic, supporting arbitrary size entries up to
+ * PAGE_SIZE.
+ *
+ * A genradix is defined with the type it will store, like so:
+ *
+ * static GENRADIX(struct foo) foo_genradix;
+ *
+ * The main operations are:
+ *
+ * - genradix_init(radix) - initialize an empty genradix
+ *
+ * - genradix_free(radix) - free all memory owned by the genradix and
+ * reinitialize it
+ *
+ * - genradix_ptr(radix, idx) - gets a pointer to the entry at idx, returning
+ * NULL if that entry does not exist
+ *
+ * - genradix_ptr_alloc(radix, idx, gfp) - gets a pointer to an entry,
+ * allocating it if necessary
+ *
+ * - genradix_for_each(radix, iter, p) - iterate over each entry in a genradix
+ *
+ * The radix tree allocates one page of entries at a time, so entries may exist
+ * that were never explicitly allocated - they will be initialized to all
+ * zeroes.
+ *
+ * Internally, a genradix is just a radix tree of pages, and indexing works in
+ * terms of byte offsets. The wrappers in this header file use sizeof on the
+ * type the radix contains to calculate a byte offset from the index - see
+ * __idx_to_offset.

+ * PG_reserved is set for special pages. The "struct page" of such a page
+ * should in general not be touched (e.g. set dirty) except by its owner.
+ * Pages marked as PG_reserved include:
+ * - Pages part of the kernel image (including vDSO) and similar (e.g. BIOS,
+ * initrd, HW tables)
+ * - Pages reserved or allocated early during boot (before the page allocator
+ * was initialized). This includes (depending on the architecture) the
+ * initial vmemmap, initial page tables, crashkernel, elfcorehdr, and much
+ * much more. Once (if ever) freed, PG_reserved is cleared and they will
+ * be given to the page allocator.
+ * - Pages falling into physical memory gaps - not IORESOURCE_SYSRAM. Trying
+ * to read/write these pages might end badly. Don't touch!
+ * - The zero page(s)
+ * - Pages not added to the page allocator when onlining a section because
+ * they were excluded via the online_page_callback() or because they are
+ * PG_hwpoison.
+ * - Pages allocated in the context of kexec/kdump (loaded kernel image,
+ * control pages, vmcoreinfo)
+ * - MMIO/DMA pages. Some architectures don't allow to ioremap pages that are
+ * not marked PG_reserved (as they might be in use by somebody else who does
+ * not respect the caching strategy).
+ * - Pages part of an offline section (struct pages of offline sections should
+ * not be trusted as they will be initialized when first onlined).
+ * - MCA pages on ia64
+ * - Pages holding CPU notes for POWER Firmware Assisted Dump
+ * - Device memory (e.g. PMEM, DAX, HMM)
+ * Some PG_reserved pages will be excluded from the hibernation image.
+ * PG_reserved does in general not hinder anybody from dumping or swapping
+ * and is no longer required for remap_pfn_range(). ioremap might require it.
+ * Consequently, PG_reserved for a page mapped into user space can indicate
+ * the zero page, the vDSO, MMIO pages or device memory.

+ * There can be more then one JOB per queue.

+ * internal. The driver will get completion notifications from the device only
+ * on JOBS which are enqueued in the external queues.
+ *
+ * For jobs on external queues, the user needs to create command buffers
+ * through the CB ioctl and give the CB's handle to the CS ioctl. For jobs on
+ * internal queues, the user needs to prepare a "command buffer" with packets
+ * on either the SRAM or DRAM, and give the device address of that buffer to
+ * the CS ioctl.
+ *
+ * This IOCTL is asynchronous in regard to the actual execution of the CS. This
+ * means it returns immediately after ALL the JOBS were enqueued on their
+ * relevant queues. Therefore, the user mustn't assume the CS has been completed
+ * or has even started to execute.
+ *
+ * Upon successful enqueue, the IOCTL returns an opaque handle which the user
+ * can use with the "Wait for CS" IOCTL to check whether the handle's CS
+ * external JOBS have been completed. Note that if the CS has internal JOBS
+ * which can execute AFTER the external JOBS have finished, the driver might
+ * report that the CS has finished executing BEFORE the internal JOBS have
+ * actually finish executing.
+ *
+ * The CS IOCTL will receive three sets of JOBS. One set is for "restore" phase,
+ * a second set is for "execution" phase and a third set is for "store" phase.
+ * The JOBS on the "restore" phase are enqueued only after context-switch
+ * (or if its the first CS for this context). The user can also order the
