Subject: [pbs-devel] [PATCH proxmox] async: runtime: fix `block_in_place` panicking in wrong runtime
Date: Thu, 17 Aug 2023 18:46:37 +0200	[thread overview]
Message-ID: <20230817164637.1286178-1-m.carrara@proxmox.com> (raw)

Because `tokio::task::block_in_place` panics if called in the
"current_thread" runtime, so does our wrapper function.

This is fixed by checking whether we're actually in a multithreaded
tokio runtime.
