From b7107e758f4ecdd8f07ede3f093cbbfdb623e865 Mon Sep 17 00:00:00 2001 From: Roman Kagan Date: Thu, 11 Nov 2021 18:33:45 +0300 Subject: vhost-user-blk: reconnect on any error during realize vhost-user-blk realize only attempts to reconnect if the previous connection attempt failed on "a problem with the connection and not an error related to the content (which would fail again the same way in the next attempt)". However this distinction is very subtle, and may be inadvertently broken if the code changes somewhere deep down the stack and a new error gets propagated up to here. OTOH now that the number of reconnection attempts is limited it seems harmless to try reconnecting on any error. So relax the condition of whether to retry connecting to check for any error. This patch amends a527e312b5 "vhost-user-blk: Implement reconnection during realize". Signed-off-by: Roman Kagan Message-Id: <20211111153354.18807-2-rvkagan@yandex-team.ru> Reviewed-by: Michael S.
