Subject: [PATCH] vhost-user-blk: reconnect on any error during realize
|
|
|
|
cherry picked from commit b7107e758f4ecdd8f07ede3f093cbbfdb623e865
|
|
|
|
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".
