You'd be much more efficient if you just did

	git fetch linus

which avoids switching back-and-forth (and speeds up the pull too, since 
it doesn't need to update any working directories).

No, don't do this.

"git resolve" is the _old_ stupid merger, which isn't very helpful at all. 
So please use

	git merge "Merge with Linus" work linus

instead, which will use the proper "recursive" merge functionality.

Yeah, "git rebase" is not _nearly_ as intuitive as doing a real merge.

What happened was that you resolved the thorny merge, but the rebase had 
stopped when it hit it, so it never actually did the rest of the rebase. 
Which explains why some of your changes are no longer present: they are 
still in the "rebase queue".

Yes, but you missed the fact that unlike "git merge", rebasing really is a 
"move one commit at a time" thing, and it stopped on the middle.

You should never do "resolve", it's very oldfashioned. If you want to 
merge, just use "git merge", which will do the right thing.

As to rebase, it often is very nice, but on the other hand, it leaves 
things in a total mess when it fails, which is a pity. Maybe there's a 
nice way to just continue, but I end up just doing a

	git reset --hard ORIG_HEAD

to undo the failed rebase.

Junio, is there some magic to restart a rebase after you've fixed up the 
conflicts?
