Hi guys, I have a quick (kind of dumb) question for you about journaling. I know that ext4 postpones checkpoints in data journaling mode, i.e., most of data (and meta-data) are only written to the journal and checkpointed to their final location only when certain thresholds are crossed. My question is: how do ext4 handle read operations to data blocks that are only written to the journal (supposing that its cache has been evicted)? Does it execute the read operation in the journaled data? Does it trigger a checkpoint? Probably I'm missing something here.
