+ *   o fsck looks if it can find the fsck.type program to decide

+ * rehash.c --- rebuild hash tree directories

+ * This algorithm is designed for simplicity of implementation and to

+ * as much memory as the size of the directory.  The maximum size
+ * directory supported using a 4k blocksize is roughly a gigabyte, and
+ * so there may very well be problems with machines that don't have
+ * virtual memory, and obscenely large directories.
+ *
+ * An alternate algorithm which is much more disk intensive could be
+ * written, and probably will need to be written in the future.  The
+ * design goals of such an algorithm are: (a) use (roughly) constant
+ * amounts of memory, no matter how large the directory, (b) the
+ * directory must be safe at all times, even if e2fsck is interrupted
+ * in the middle, (c) we must use minimal amounts of extra disk
+ * blocks.  This pretty much requires an incremental approach, where
+ * we are reading from one part of the directory, and inserting into
+ * the front half.  So the algorithm will have to keep track of a
+ * moving block boundary between the new tree and the old tree, and
+ * files will need to be moved from the old directory and inserted
+ * into the new tree.  If the new directory requires space which isn't
+ * yet available, blocks from the beginning part of the old directory
+ * may need to be moved to the end of the directory to make room for
+ * the new tree:
+ *
+ *    --------------------------------------------------------
+ *    |  new tree   |        | old tree                      |
+ *    --------------------------------------------------------
+ *                  ^ ptr    ^ptr
+ *                tail new   head old
+ *
+ * This is going to be a pain in the tuckus to implement, and will
+ * require a lot more disk accesses.  So I'm going to skip it for now;
+ * it's only really going to be an issue for really, really big
+ * filesystems (when we reach the level of tens of millions of files
+ * in a single directory).  It will probably be easier to simply
+ * require that e2fsck use VM first.

+ * linux/fs/revoke.c
+ *
+ * Journal revoke routines for the generic filesystem journaling code;
+ * part of the ext2fs journaling system.
+ *
+ * Revoke is the mechanism used to prevent old log records for deleted
+ * metadata from being replayed on top of newer data using the same
+ * blocks.  The revoke mechanism is used in two separate places:
+ *
+ * + Commit: during commit we write the entire list of the current
+ *   transaction's revoked blocks to the journal
+ *
+ * + Recovery: during recovery we record the transaction ID of all
+ *   revoked blocks.  If there are multiple revoke records in the log
+ *   for a single block, only the last one counts, and if there is a log
+ *   entry for a block beyond the last revoke, then that log entry still
+ *   gets replayed.
+ *
+ * We can get interactions between revokes and new log data within a
+ * single transaction:
+ *
+ * Block is revoked and then journaled:
+ *   The desired end result is the journaling of the new block, so we
+ *   cancel the revoke before the transaction commits.
+ *
+ * Block is journaled and then revoked:
+ *   The revoke must take precedence over the write of the block, so we
+ *   need either to cancel the journal entry or to write the revoke
+ *   later in the log than the log block.  In this case, we choose the
+ *   latter: journaling a block cancels any revoke record for that block
+ *   in the current transaction, so any revoke for that block in the
+ *   transaction must have happened after the block was journaled and so
+ *   the revoke must take precedence.
+ *
+ * Block is revoked and then written as data:
+ *   The data write is allowed to succeed, but the revoke is _not_
+ *   cancelled.  We still need to prevent old log records from
+ *   overwriting the new data.  We don't even need to clear the revoke
+ *   bit here.
+ *
+ * Revoke information on buffers is a tri-state value:
+ *
+ * RevokeValid clear:   no cached revoke status, need to look it up
+ * RevokeValid set, Revoked clear:
+ *                      buffer has not been revoked, and cancel_revoke
+ *                      need do nothing.
+ * RevokeValid set, Revoked set:
+ *                      buffer has been revoked.
