Managing linux-next tree

Hi,

I've been following linux-next tree and base some of my janitorial realted work on this tree. Things are fine, but I think I'm little confused with the git branching/merging stuff. Please find some of the steps that I follow to clone and update my local linux-next tree:

1. Clone the tree (once):

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git

So here I've just one branch called master. To work on some code cleanup work etc, I create my private branch (see step 2 below)

2. Create my private branch based on latest tag(every now and then)

$ git tag -l next-*|tail -n 1
next-20130709
$ git checkout next-20130709
$ git checkout -b July-09

So, Now i have two branches; master and July-09, and I commit any changes in July-09 branch. Later (say after some days) I fetch remote changes.

3: Fetch remote changes

$ git remote update

Now, I delete the old branch(let's forget about the commits that I made it to July-09 branch for a moment) and create another private branch by following the steps mentioned above in step 2. It is fine but when I invoke git command to get the status of the working tree(say master, remember I've just issued 'git remote update'), it tells me that my branch and 'origin/master' have diverged. steps, as in 4:
4: Get the information on working tree status

$ git checkout master			# switch back to master
$ git remote update			# Fetch remote updates
Fetching origin
remote: Counting objects: 29053, done.
remote: Compressing objects: 100% (4329/4329), done.
.......
.......

* [new tag] v3.11-rc3 -> v3.11-rc3

$ git branch -D July-09  		# deleting the old branch
$ git branch				# Left with master now
* master
$ git checkout next-20130801 -b Aug-01  # Creating once again a new branch
$ git branch
* Aug-01	<--- Currently on Aug-01
  master
$ git status
# On branch Aug-01
nothing to commit (working directory clean)
$ git checkout master  			# Switch back to master once again
$ git branch
  Aug-01
* master	<--- Currently on master

$ git status				# get the working tree status	
# On branch master
# Your branch and 'origin/master' have diverged, <-------------------+ 
# and have 368 and 3227 different commit(s) each, respectively. <----+
#
nothing to commit (working directory clean)

So, What should I do to keep my local master in sync with the remote origin/master ? Will a 'git pull' work ? Actually I tried 'git pull', but it gave me some warning messages, hence I interrupted(CTRL-c) this in between <snip>

$ git pull
warning: too many files (created: 926 deleted: 310), skipping inexact rename
detection
warning: too many files (created: 4620 deleted: 3979), skipping inexact rename
detection
warning: too many files (created: 1256 deleted: 405), skipping inexact rename
detection

This won't do what you want. What you want is something more like:

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ git remote add linux-next git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
$ git fetch linux-next
$ git fetch --tags linux-next

which will leave you a linux-next tree that you can update.

This will *not* work on linux-next. Once you build the tree as above,
you want to use 'git remote update' instead of pull.
