From 3e3876d322aef82416ecc496a4d4a587e0fdf7a3 Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Wed, 13 Apr 2022 16:48:36 +0800 Subject: [PATCH] block: null_blk: end timed out poll request When poll request is timed out, it is removed from the poll list, but not completed, so the request is leaked, and never get chance to complete. Fix the issue by ending it in timeout handler.
