Climbing evening.

That was quite short although quite hard training. After number of warming traverses I started jumping again - now I created a 'trace' myself of the huge horizontal negative slope, so some times I fell to the back from about meter, which was even fun. Eventually I managed to complete own jumping holds, which resulted in a very rubbed fingers both on feet and arms, so essentially rest of the training was predefined to be something trivial. Nevertheless I managed to try some old complex start couple of times, fell of course, but it was worth it.
Usual finish of the training - sauna - today was exceptionally dry and hot - about 99 degres Centigrade and it was even hard to breath, since air was so dry.
Anyway, excellent time!

Unhashed inodes can not be synced during writeback.

So essentially there is no way to implement own inode cache tied to system's writeback mechanism, which is a bad news. POHMELFS in its current reincarnation does not use system's inode cache and all its indeas are unhashed, which results in a fact, that they are never synced, since writeback mechanism just does not see them.
So I will fallback to hashed inodes, which will be used just for that, and writeback for single inode will end up creating directory structure for the all upper layer objects.

Another idea is to implement own writeback, which would be scheduled from the main one or after memory notifications, this approach has lots of advantages actually, but let's first complete simpler part with hased inodes.

This is called learning curve - I'm essentially where I was before, but with extended baggage of knowledge.
