I did a git remove update...

Lemme double check:

[acme@zoo babeltrace]$ git remote update
Fetching origin
[acme@zoo babeltrace]$ git remote -v
origin git://git.efficios.com/babeltrace.git (fetch)
origin git://git.efficios.com/babeltrace.git (push)
[acme@zoo babeltrace]$ git log --oneline | head -1
48d711a204f6 Fix: Missing stdint.h in stream-class.h
[acme@zoo babeltrace]$

What is wrong here? Is it in a different branch?

/me checks again that... Yeah, I probably created my local branch from
some other branch, now that I did:

[acme@zoo babeltrace]$ git checkout -b master origin/master
Branch master set up to track remote branch master from origin.
Switched to a new branch 'master'
[acme@zoo babeltrace]$ git log --oneline | head -1
d8f190b24d52 Add tests for bt_ctf_field_string_append_len()
[acme@zoo babeltrace]$

will try again those patches...
