Hi Dopi,
Don't want to run too off-topic, but I've been thinking about moving
to EXT4 for further speed improvements. However by default there is 2
min delayed write with EXT4 which can cause data loss if the phone
were to crash before a write was 'sync'ed. However this was patched in
kernel 2.6.30 to allow for it to be switched off (alloc_on_commit).
Therefore at some point when we do move past .29 we could start using
EXT4 instead of EXT3 as well. Although we could apply the patch to the
current kernel and enable EXT4 support sooner?
Also don't know if you are aware of the following git repository?
http://git.kernel.org/?p=linux/kernel/git/kki_ap/linux-2.6-samsung.git
Cheers,
Kaes
