On the other hand if the LVM2 + thin pool + EXT4/XFS combo was used instead of btrfs,
you would get much of the benefits of btrfs (COW snapshots, space allocation from a pool, etc.)
and you could just easily create a new logical volume in the volume group and use that for swap. :)
I wonder *how bad* loop mount performance is for swap?

Haven't read much of this thread (sorry, busy :) ) but the impression I got was that most of the people complaining about app-killing accept that massive slowdowns / 'thrashing' is the only alternative.

As long as it's still moving fast enough to take remedial action and free up some RAM...

Seems to be working fine - shows time, date, day of the week and notifications. btw, seems also TOHKBD is working in Android :)

Forget about swap on flash media, whether it be on raw disk partition or on top of filesystem...
Swap on flash is a BAD IDEA and it WILL kill your flash.

Glance screen is there!
And i grasped how the unlock fade works.

If the glance screen is activated and you doubletap while the clock is shown, the clock just changes color and the lockscren comes faded in its background.

If you unlock without the glance screen shown, from blank screen, the clock fades in last after the lockscreen has already completely faded in.
That is rather inconvenient and needs to be adjusted to have consistant behaviour and clock shown fast.

And so will recording HD video, downloading files/cache from the Internet, logging... and a shitton other stuff that I do daily with the phone.

It's not clear to me why swapping would be a more dangerous activity, since it's mostly sequential, low persistence requirements, and most importantly... it happens rarely, less frequently than all the above combined.

And besides, Jolla already has a swap partition. I'm just considering removing any hardcoded limits to it.

Set swappiness to a very low value, and it'll only use it when it has to. Besides which flash is generally nowhere near as fragile as it used to be. I don't know how much that extends to the chips in phones, but I'd be surprised if you could kill it appreciably faster by just having that in place when RAM runs out - the user's likely to avoid that situation because of the system slowing to a crawl more than anything else I'd have thought.

ETA - screw it, put it on an SD card. Yes, it'll be eye-wateringly slow, but it'll (presumably) stop the automatic program closures, and if you manage to fry it you can put a new one in...

And, pray tell, what alternative do you suggest?

More memory and no swap? ;)

My single biggest issue is the size of the clock when peeking. "1.0" used to show lockscreen clock which was huge and could be seen easily, now the text is really small and hard to read with a layer on top of it
