ext2 large block size > page size

[Mason <mpeg.blue@free.fr>]

Hello everyone,

As far as I can tell from a quick Google search,
there was a push in 2007 to add support for large
blocks in some file-systems, in particular ext2.

e.g. cf. http://lwn.net/Articles/239090/

Was this ever accepted into the main line?
(It seems to have lived within -mm for a while)

A few years later, I'm trying to mount a HDD
which was ext2-formatted with 32k blocks.

And mount is failing (with a strange "block size
too small" error message).

I'm trying this in Fedora 14
2.6.35.6 kernel
1.41.12 e2fsprogs

Is the support for large blocks in ext2 not compiled in
this generic kernel ? Or was the patch never accepted ?

I'm working with a ST Microelectronics set-top box.
Here are a few performance results for a 2TB USB HDD:
block size  4k  :  format = 151 s / mount = 242 s
block size  8k  :  format =  52 s / mount =  71 s
block size 16k  :  format =  30 s / mount =  36 s
block size 32k  :  format =  18 s / mount =  19 s

Using 4kB blocks makes mount too slow on the STB, which
is why I'd like to use larger blocks. It would be nice
if the movies recorded on the STB could also be read on
a Linux PC.
