ext4: enable FITRIM ioctl on bigalloc file system
With a minor tweaks regarding minimum extent size to discard and discarded bytes reporting the FITRIM can be enabled on bigalloc file system and it works without any problem. This patch fixes minlen handling and discarded bytes reporting to take into consideration bigalloc enabled file systems and finally removes the restriction and allow FITRIM to be used on file system with bigalloc feature enabled.
