    ext4: add EXT4_IOC_ALLOC_DA_BLKS ioctl · ccd2506b
    Theodore Ts'o authored
    Add an ioctl which forces all of the delay allocated blocks to be
    allocated.  This also provides a function ext4_alloc_da_blocks() which
    will be used by the following commits to force files to be fully
    allocated to preserve application-expected ext3 behaviour.
