[PATCH for 5.10-6.1 0/4] rbd: fix a deadlock around header_rwsem and lock_rwsem

Hello,

Patch 1/4 needed a trivial adjustment, the rest were taken verbatim and included here just for convenience.

Thanks,

Ilya

Ilya Dryomov (4): rbd: move rbd_dev_refresh() definition rbd: decouple header read-in from updating rbd_dev->header rbd: decouple parent info read-in from updating rbd_dev rbd: take header_rwsem in rbd_dev_refresh() only when updating
