    ext4: discard preallocations after removing space · ef24f6c2
    Lukas Czerner authored
    Currently in ext4_collapse_range() and ext4_punch_hole() we're
    discarding preallocation twice. Once before we attempt to do any changes
    and second time after we're done with the changes.
    
    While the second call to ext4_discard_preallocations() in
    ext4_punch_hole() case is not needed, we need to discard preallocation
    right after ext4_ext_remove_space() in collapse range case because in
    the case we had to restart a transaction in the middle of removing space
    we might have new preallocations created.
    
    Remove unneeded ext4_discard_preallocations() ext4_punch_hole() and move
    it to the better place in ext4_collapse_range()
