WRT atomic LEB caches and barriers - I guess if there are users who
would prefer higher I/O speed to the power-cut tolerance, you could:
1. ignore I/O barriers
2. use plain leb_unmap/leb_write instead of atomic leb change, which is
faster.
There could be a switch, probably an ioctl? But this is not very
important now, I am just throwing an idea.
