From 59ac9c078141b8fd0186c0b18660a1b2c24e724e Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 4 May 2017 15:50:47 -0700 Subject: [PATCH] target/fileio: Fix zero-length READ and WRITE handling This patch fixes zero-length READ and WRITE handling in target/FILEIO, which was broken a long time back by: Since: commit d81cb44726f050d7cf1be4afd9cb45d153b52066 Author: Paolo Bonzini Date: Mon Sep 17 16:36:11 2012 -0700 target: go through normal processing for all zero-length commands which moved zero-length READ and WRITE completion out of target-core, to doing submission into backend driver code. To address this, go ahead and invoke target_complete_cmd() for any non negative return value in fd_do_rw().
