Hello, Current. It was explained to me, that all three GEOM threads (up, down and ctl) could not execute code, which should sleep. It looks sound for up and down, but not for ctl, but it is so now. So, I have question: what should I do if I need to perofrm ONE action, which could block for some time (for example, open file or create ALQ)? I could create thread for this. But it looks strange and too heavy: create thread to call one function once. Maybe, kernel has some API to postpone such task to one, always-running idle thread? -- // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>help
