[PATCH 0/6] Protect the block layer with a rwlock: part 2

[Emanuele Giuseppe Esposito]

Please read "Protect the block layer with a rwlock: part 1" for an additional
introduction and aim of this series.

This second part aims to add the graph rdlock to the BlockDriver functions
that already run in coroutine context and are classified as IO.
Such functions will recursively traverse the BlockDriverState graph, therefore
they need to be protected with the rdlock.

Based-on: <20221116134850.3051419-1-eesposit@redhat.com>

Thank you,
Emanuele
