This is the change of the kernel side.
Transition of logical to inode used to have a limit 4096 on inode container's
size, but the limit is not large enough for a data with a great many of refs,
so when resolving logical address, we can end up with
"ioctl ret=0, bytes_left=0, bytes_missing=19944, cnt=510, missed=2493"
This changes to regard 4096 as the lowest limit.
