I wonder about a way to find out directly

1) size of node and leaf metadata blocks

2) whether inode cache is active

3) whether space cache is active

Would also be nice to be able to set this. I do not know whether this is 
possible re 1 during a balance for example. Re 2 and 3 it would be nice to 
be able to skip the mount options in /etc/fstab. AFAIK space cache is 
permanent anyway, but inode cache isn´t or vice versa.

Either way I find the current way BTRFS handles options via mount options a 
bit confusion.

I´d like some way to set attributes / flags permanently like in Ext4 via 
tune2fs or xfs_admin.

Thanks,
