Add chmod command to debugfs.

-block_illegal_map should be only created in pass1b.c, since it isn't
-used anywhere else.

------------------------------------------
fix up get_backup_sb, so that it doesn't choose something bogus if
ncheck <inode>

+Add a filesystem creation date to the superblock

+Subject: DEBUGFS - thanks and a feature idea
+Content-Type: TEXT/PLAIN; charset=US-ASCII
+
+Theodore:
+
+First, let me thank you for writing debugfs. Recently, my Linux box
+(RH 6.0, 400 MHz PIII, on a DSL line) was hacked into. The intruder did
+an "rm -Rf" on a 34 GB drive with about 5GB of data on it. I was able to
+restore essentially the entire thing with debugfs and a bit of C code and Perl.
+Actually, I could have done the entire thing with debugfs and Perl, but I
+thought it would be too slow.
+
+During this exercise, I noticed that one small feature was lacking that would
+have made my job a bit easier. The length of a deleted directory is
+reported as 0, hence debugfs won't dump the contents of the directory to a
+file using the "dump" command. The only thing that saved me was that the
+list of disk blocks is not zeroed out. I was able to dump the contents of the
+directories by using debugfs to get the relevant block numbers, then
+using dd to get the actual data.
+
+If debugfs had a feature where it ignored the size of a directory reported by
+the inode and instead just dumped all the blocks, it would have facilited
+things a bit. This seems like a very easy feature to add.
+
+Again, thanks for writing debugfs (and all the other Linux stuff you've written!).
+
+Cheers,

+
+a) An option to mkfs to run badblocks in read/write mode. The
+filesystem is blank, so this is the perfect time to run the read/write
+test.
+
+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.
