- already pushing a mirror to github -

Funny thing is that several GalaxyS developers found this non secret at all repository about 2 months ago, but we didn't knew back then that Nexus S will exist, neither how to use these sources.
Now we do !

What does it tells for us Galaxy S developers:
- we can borrow some bugfixes from the 2.6.35 kernel version, for all the Galaxy S phones
- we can study how the Nexus S drives the 512MB OneNAND device, using YAFFS2
- some of the closed components on Galaxy S kernel may be free now in Nexus S.

EDIT:
Nexus S kernel built for GalaxyS.
Boot, give you a shell. Nothing more. Can be use to analyze things ;)

Do you think we might be able to see some of the Nexus S kernel, graphics, GPS improvements on Galaxy S soon?

Also, this doesn't provide the full ROM (i.e. Gingerbread source), just kernel/drivers right?

Only 2 more days until we can get a Nexus S dump though!

lagfix is nothing but a file format change from RFS to ext4. So long as Galaxy S defaults to RFS, we need to change it to ext4 and it will be "called" a lagfix.

PS; and in Nexus S it WONT be called a lagfix because it is the default.
