I see the man page changes were added in "e2fsck: misc cleanups for pfsck", which I would have merged into other patches, but that's a bit of a nit-pick. (The way I normally do these sorts of changes is to expert the patches using "git format-patch", and then I'll use an editor to move patch hunks around, and then apply them all using "git am". Or I'll using something like the "guilt" program, which is essentially quilt for git patch series.) (Don't worry about making changes for this, unless you're going to be making lots of other changes to the patch series.) - Ted
