i just read about the veritas filesystem (well, yeah, it existed a long time ago..) and was wondering if journaling is ever going to be added to ext2fs. what must be added/modified to the driver code to support an intent log? i think basic journaling code would "only" require addition of an intent log (where?) and add reading of this log to e2fsck..
Adding journalling isn't so simple. One, you need ordered writes, which is something the low-level block device interface doesn't provide. Secondly, you have to worry about performance, which is hard to do while still having the ordering semantics.
