Barelvi is a misnomer used for non-deobandi sufism followers. Barelvis are those UP origin muslims who follow a man called Ahmed Raza Barelvi.
Anyways the majority of sufism followers supported Pakistan but Ahmed Raza Barelvi's descendants still live in India because they did not accept Pakistan. So technically the head of Barelvism did not accept Pakistan in 1947. He preferred to remain in India (Ahmed Raza's son).
Majority of Deoandis opposed Pakistan. So much so the twelver Shia headquarter which is based in Lukcnow also did not accept Pakistan and preferred to stay in India. The head of Ismaili Shia Agha Khan accepted Pakistan though.
