Re: [Xen-users] how to reduce time of git pulling each time when you do a make world on Xen source

[Patrick Scharrenberg <pittipatti@xxxxxx>]

You can take a look into the Makefile:
there you'll find e.g.:

world: 
        $(MAKE) clean
        $(MAKE) kdelete
        $(MAKE) dist

so what a "make world" does is
   make clean
   make kdelete
and finally
   make dist

so if you solely do a "make dist" the build process skips the deletition of 
the compiled binary objects (make clean) and skips deleting your checked out 
kernel tree (make kdelete)

so a "make dist" after an upgraded working copy (hg pull -u) only compiles the 
files which have changed, which saves time.

Please have a look at the Makefile, do a "make help" and take a look at the 
README file for further information.
