Subject: FIEMAP patches

I read through the entire previous FIEMAP thread (phew!) and it boils
down mostly to:

s/FIEMAP_FLAG_NO_DIRECT/FIEMAP_FLAG_NO_BYPASS/

> * FIEMAP_EXTENT_UNWRITTEN                                                    
> Unwritten extent - the extent is allocated but it's data has not been        
> initialized.  This indicates the extent's data will be all zero.             
                                                                               
This should say "will be all zero if read through the filesystem              
but the contents are undefined if read directly from the device."

There was also an update to the ext4 patch from Kalpak for handling
EA-in-inode at the same time as an external inode.

Eric, Mark,
could one of you please just submit the patches to Andrew for inclusion.
I think there was plenty of debate already, with very little significant
benefit except suggesting different names for some of the flags.

Cheers, Andreas
