Hmm isn't this basically what ext4_move_extents() does ? eg.
EXT4_IOC_MOVE_EXT ?
I guess that the intention he
This patch implements fs ioctl's IOC_MOV_DATA for Ext4.
The semantics of this ioctl are:
1) Like collapse range, offsets and length should be file system block size
aligned.
2) In the receiver file, atleast length size hole should be present at
receiver_offset
3) It does not change file size
