+/*
+ * On-disk structures.
+ *
+ * THE BIG PICTURE of on-disk layout:
+ *
+ * GFS filesystem code views the entire filesystem, including journals, as
+ * one contiguous group of blocks on one (perhaps virtual) storage device.
+ * The filesystem space is shared, not distributed; each node in the cluster
+ * must see the entire filesystem space.
+ *
+ * If the filesystem is spread across multiple physical storage devices,
+ * volume management (device mapping) must be used to present the fileystem
+ * space to GFS as one (virtual) device, with contiguous blocks.
+ *
+ * The superblock contains basic information about the filesytem, and appears
+ * at a location 64 KBytes into the filesystem. The first 64 KBytes of the
+ * filesystem are empty, providing a safety buffer against wayward volume
+ * management software (that sometimes write data into the first few bytes of
+ * a device) or administrators.
+ *
+ * After the superblock, the rest of the filesystem is divided into multiple
+ * Resource Groups and several journals.
+ *
+ * The Resource Groups (RGs or rgrps) contain the allocatable blocks that are
+ * used for storing files, directories, etc., and all of the associated
+ * metadata. Each RG has its own set of block allocation statistics (within
+ * the RG header), a number of blocks containing the block allocation bitmap,
+ * and a large number of allocatable blocks for file data and metadata.
+ * Multiple RGs allow multiple nodes to simultaneously allocate blocks from the
+ * filesystem (using different RGs), enhancing parallel access. RG size and
+ * number of RGs are determined by gfs_mkfs when creating the filesystem.
+ * An administrator can specify RG size (see man gfs_mkfs).
+ *
+ * The journals contain temporary copies of metadata blocks, along with
+ * other data, that allow GFS to recover the filesystem to a consistent state
+ * (at least as far as metadata is concerned) if a node fails in the midst
+ * of performing a write transaction. There must be one journal for each node
+ * in the cluster. Since access to the entire filesystem space is shared,
+ * if a node crashes, another node will be able to read the crashed node's
+ * journal, and perform recovery.
+ *
+ * Currently, gfs_mkfs places the journals right in the middle of a freshly
+ * created filesystem space, between 2 large groups of RGs. From a filesystem
+ * layout perspective, this placement is not a requirement; the journals
+ * could be placed anywhere within the filesystem space.
+ *
+ * New Resource Groups and Journals may be added to the filesystem after the
+ * filesystem has been created, if the filesystem's (virtual) device is made
+ * larger. See man gfs_grow and gfs_jadd.
+ *
+ * A few special hidden inodes are contained in a GFS filesystem. They do
+ * not appear in any directories; instead, the superblock points to them
+ * using block numbers for their location. The special inodes are:
+ *
+ * Root inode: Root directory of the filesystem
+ * Resource Group Index: A file containing block numbers and sizes of all RGs
+ * Journal Index: A file containing block numbers and sizes of all journals
+ * Quota: A file containing all quota information for the filesystem
+ * License: A file containing license information
+ *
+ * Note that there is NOTHING RELATED TO INTER-NODE LOCK MANAGEMENT ON-DISK.
+ * Locking is handled completely off-disk, typically via LAN.
+ *
+ * NOTE:
+ * If you add 8 byte fields to these structures, they must be 8 byte
+ * aligned. 4 byte field must be 4 byte aligned, etc...
+ *
+ * All structures must be a multiple of 8 bytes long.
+ *
+ * GRIPES:
+ * We should have forgetten about supporting 512B FS block sizes
+ * and made the di_reserved field in the struct gfs_dinode structure
+ * much bigger.
+ *
+ * de_rec_len in struct gfs_dirent should really have been a 32-bit value
+ * as it now limits us to a 64k FS block size (with the current code
+ * in dir.c).

+ * Generic metadata head structure
+ *
+ * Every inplace buffer logged in the journal must start
+ * with a struct gfs_meta_header.
+ *
+ * In addition to telling what kind of metadata is in the block,
+ * the metaheader contains the important generation and incarnation
+ * numbers.
+ *
+ * The generation number is used during journal recovery to determine
+ * whether an in-place block on-disk is older than an on-disk journaled copy
+ * of the block. If so, GFS overwrites the in-place block with the journaled
+ * version of the block.
+ *
+ * A meta block's generation number must increment monotonically across the
+ * cluster, each time new contents are committed to the block. This means
+ * that whenever GFS allocates a pre-existing metadata block, GFS must read
+ * that block from disk (in case another node has incremented it). It also
+ * means that GFS must sync the block (with incremented generation number)
+ * to disk (both log and in-place blocks), not only after changing contents
+ * of the block, but also after de-allocating the block (GFS can't just throw
+ * away incore metadata for a file that it's just erased).
+ *
+ * The incarnation number is used only for on-disk (d)inodes. GFS increments
+ * it each time it de-allocates a dinode block (i.e. each time the dinode
+ * loses its identity with a particular file, directory, etc.). When the
+ * dinode is later allocated (i.e. to be identified with a new file, etc.),
+ * GFS copies the incarnation number into the VFS inode's i_generation member.
+ * If GFS is used as the backing store for an NFS server, GFS uses this
+ * i_generation number as part of the NFS filehandle, which differentiates
+ * it from the previous identity of the dinode, and helps protect against
+ * filesystem corruption that could happen with the use of outdated,
+ * invalid, or malicious filehandles. See ops_export.c.
+ *
+ * GFS caches de-allocated meta-headers, to minimize disk reads.
+ * See struct gfs_meta_header_cache.
