-	* rehash.c --- rebuild hash tree directories
-	*
-	* This algorithm is designed for simplicity of implementation and to
-	* pack the directory as much as possible. It however requires twice
-	* 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.
