[PATCH v4 07/11] tests/virtio-9p: failing splitted readdir test |
Date: |
Tue, 21 Jan 2020 01:17:35 +0100 |
This patch is not intended to be merged. It resembles
an issue (with debug messages) where the splitted
readdir test fails because server is interrupted with
transport error "Failed to decode VirtFS request type 40",
which BTW fails both with the unoptimized and with the
optimized 9p readdir code.
