debugfs/ChangeLog

2002-02-25  Theodore Tso  <tytso@mit.edu>

	* util.c (open_pager): If the PAGER environment is set to __none__
		then don't use a pager at all, and ship it all to stdout.

		implements the three new commands, htree_dump, dx_hash,
		and dirsearch.

	* debugfs.c (do_undel, do_testb, do_freeb, do_setb, do_ffb): Add
		new command, undelete, which automates undeleting a

2001-12-23  Theodore Tso  <tytso@mit.edu>

	* Makefile.in, jfs_user.h: Move linux/jbd.h to
		ext2fs/kernel-jbd.h, to avoid using the system header
		file version of hbd.h when using diet glibc (since it
		forcibly adds /usr/include to the beginning of the
		include search path.)

		an long long variable.

2001-11-24  Theodore Tso  <tytso@mit.edu>

	* debugfs.8.in: Update manual page to document the set_super_value
		and logdump commands, and move the "specifying files"
		section closer to the beginning of the man page so people
		won't miss it.

	* setsuper.c (print_possible_fields): "set_super_value -l" now
		prints out the list of valid superblock fields which the
		ssv command can set.
