ext4 had a bug for files with indirect extents where it wrongly reported a size of a hole in some cases and thus SEEK_DATA implementation could skip some data in a file. Test for that. The problem is fixed by patch "ext4: Fix hole length detection in ext4_ind_map_blocks()".

# Check that SEEK_DATA works properly for offsets in the middle of large holes.

# This was broken for ext4 with indirect-block based files and this test checks
