From: Bob Peterson <rpeterso@xxxxxxxxxx> [ Upstream commit d0f17d3883f1e3f085d38572c2ea8edbd5150172 ] Function gfs2_clear_rgrpd calls kfree(rgd->rd_bits) before calling return_all_reservations, but return_all_reservations still dereferences rgd->rd_bits in __rs_deltree. Fix that by moving the call to kfree below the call to return_all_reservations.
