Many files:
unix.c (main): If compression is enabled on the filesystem, print a
warning message (for now).
message.c: Add new compression shortcut: @c == compress
problem.c, problem.h (PR_1_COMPR_SET): Add new error code.
pass1.c (check_blocks): If the inode has EXT2_COMPRBLK_FL flag set,
check to see if the filesystem supports compression. If it does pass
this information down to process_block() so it can treat the
compressed block flag words correctly. If not, offer to clear the
flag, since it shouldn't be set.
(process_block): If an inode has the compressed inode flag set, allow
EXT2FS_COMPRESSED_BLKADDR.
pass1b.c (process_pass1b_block, delete_file_block, clone_file_block):
pass2.c (deallocate_inode_block): Use HOLE_BLKADDR to check to see if
the block can be skipped.
ChangeLog, Makefile.in:
Makefile.in: Exclude the internationalization files from being
distributed.
ChangeLog, configure, configure.in:
configure.in: Add support for --enable-compression. This is
experimental code only for now, which is why it's under --enable test.
Once it's stable, it will always be compiled in.

b) An option to mkfs to zero the partition. Yes, it can be done with
dd, but it would be a nicer way of doing it.
+------------------------------------------------------------------
+
+Add support for in ext2fs_block_iterate() for a returning the
+compressed flag blocks to block_iterate. Change default to not return
+EXT2_COMPRESSED_BLKADDR. Change e2fsck to pass this flag in.
+
+(The old compression patches did this by default all the time, which
+is bad, since it meant e2fsck never saw the EXT2_COMPRESSED_BLKADDR
+flagword.
+
+------------------------------------------------------------
+
+E2fsck should offer to clear all the blocks in an indirect block, not
+the entire inode, so there's better recovery for when an indirect
+block gets trashed.
