This is definitely worth doing, and as you've pointed out, there are a number of features which are in e2fsck/journal.c, which are not in debugfs/journal.c. The most notable one which I picked up on is the fast_commit code --- which is in the master/next branch, but not in the maint branch. I suggest that we move the functionality into the libsupport library first. I want to make sure we get the abstractions right before we "cast them into stone" by moving the functions to libext2fs. Libsupport is not exported outside of e2fsprogs, so if we decide we want to change function signatures, or make some functions private, we can do that more easily if we experiment with moving things into libsupport first. - Ted
