target/fileio: Fix zero-length READ and WRITE handling
commit 59ac9c078141b8fd0186c0b18660a1b2c24e724e upstream.
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 <pbonzini@redhat.com>
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().
