What's the difference between these two?
First, if ((major_hypersparse_first) && (*major_hypersparse_first < major)) should be if ((major_hypersparse_first) && (*major_hypersparse_first <= major))
And if I am not mistaken, if we're using DCSR/DCSC and major is in the hypersparse range, we are setting major_idx to major_hypersparse_idx + major_idx of the beginning of the hypersparse range. Otherwise major_idx is just major_offset.
I am not sure how these two are different.

Oh, I see, this isn't about major_idx, but this is about major_offset, let me take a closer look.

if ((major_hypersparse_first) && (*major_hypersparse_first < major))
=>
if ((major_hypersparse_first) && (major >= *major_hypersparse_first))
Otherwise, LGTM.

@jnke2016 found a bug in MG edge betweenness centrality. Upon investigation, the
major_offsetin this block of code wasn't being set correctly ifmajoris in the hypersparse region.
