They must be. The reasoning is simple:
1) one needs to acquire the ctx of all the BDSes for safe

Draining a BDS may lead to graph modifications, which in turn may result
in it and other BDS being stripped of their current references. If
bdrv_drain_all_begin() and bdrv_drain_all_end() do not keep strong
references themselves, the BDS they are trying to drain (or undrain) may
disappear right
