Subject: [PULL 18/35] block: Implement blk_{pread, pwrite}() using generated_co_wrapper
Date: Tue, 12 Jul 2022 20:06:00 +0200	[thread overview]
Message-ID: <20220712180617.1362407-19-hreitz@redhat.com> (raw)
In-Reply-To: <20220712180617.1362407-1-hreitz@redhat.com>

From: Alberto Faria <afaria@redhat.com>

We need to add include/sysemu/block-backend-io.h to the inputs of the
block-gen.c target defined in block/meson.build.
