Hi everyone !
How can I create new file in idmapped mountpoint in ext4?
I try to do the following test:
```
losetup /dev/loop1 ext4.img
mkfs.ext4 /dev/loop1
mount /dev/loop1 /mnt/ext4
./mount-idmapped --map-mount b:0:1001:1 /mnt/ext4 /mnt/idmapped1
cp testfile /mnt/idmapped1
```
then it rebacks me:
```
cp: cannot create regular file '/mnt/idmapped1/testfile': Value too
large for defined data type
```
Did I use it incorrectly?
Thanks,
Hongbo.
