Here's one from https://lkml.org/lkml/2006/6/9/183:
"Just as an example: ext3 _sucks_ in many ways. It has huge inodes that take up way too much space in memory. It has absolutely disgusting code to handle directory reading and writing (buffer heads! In 2006!). It's conditional indexing code is horrible. Its performance absolutely sucks when the journal is being drained or something.
Are you going to improve on any of those _fundamental_ problems? Or are you going to make them worse?
Hint: I'm betting you're not going to improve them by adding more features."
At the end of the day, if you lose power before the journaling FS has the chance to writes the data to disk, You WILL lose it. Period. How much damage it does depends on how much data accumulates to be written before power is lost.
BSD/FreeBSD is one of the few OSs that can survive a power hit, but who writes very much non-mission-critical stuff for BSD?
These aren't EXACTLY what I read somewhere 'back in the day', but it relates, in a way, to what I'm saying. To me, it's not that much of a stretch, but I'm stretching this too far for comfort, I'm willing to 'take a hit' on it.
It's sort of like remembering that Sarah Palin made the claim on national television that 'abstinence is unrealistic', but you can't find anything online to support that statement. However, one CAN find proof online that both Bristol Palin AND Levi Johnston, her 'baby daddy, DID say that. They both got it from SOMEWHERE...
