[coLinux-users] kernel 2.6.33-rc8 ext4

[aguspiza <agu...@ya...>]

I have tried ext4 with 2.6.33-rc8. ext4 is indeed working as module but
again as read-only ;)

trying read-write I get:

*EXT4-fs (sda4): Filesystem with huge files cannot be mounted RDWR without
CONFIG_LBDAF*

No crashes with 2.6.33-rc8 since last one.

Thank you.
