From c38ad2d339473bc90003bdb4a6c0ba576ce8b66c Mon Sep 17 00:00:00 2001 From: Evgenii Stratonikov Date: Tue, 8 Nov 2022 15:20:58 +0300 Subject: [PATCH] [#1906] writecache: Do not require `read-only` mode in `Flush` It was needed before we started to flush during transition to `degraded` mode. Now it is confusing.
