Lukas Czerner 0f2af21aae ext4: allocate entire range in zero range ... Currently there is a bug in zero range code which causes zero range calls to only allocate block aligned portion of the range, while ignoring the rest in some cases. In some cases, namely if the end of the range is past i_size, we do attempt to preallocate the last nonaligned block. However this might cause kernel to BUG() in some carefully designed zero range requests on setups where page size > block size. Fix this problem by first preallocating the entire range, including the nonaligned edges and converting the written extents to unwritten in the next step. This approach will also give us the advantage of having the range to be as linearly contiguous as possible.
