🔥 DESCRIPTION 🔥

so what does it actually do? it resumes resync on all devices that may resync now — which is exactly what the NAME said, because this page is nothing if not consistent. 💅

and here's the important little detail you're not gonna skip: it's called from process context only. read that again. process context only. the two places it comes from are the admin command and the worker. so if you were thinking about calling this from somewhere spicy, bestie, no. 🙈 that is not the move.

process context only, fr fr. admin command and worker. don't get cute with it. 💀
