mainline inclusion from mainline-5.5-rc1 commit 1a6b74fc category: feature bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=27 CVE: NA --------------------------- Right now we just copy the sqe for async offload, but we want to store more context across an async punt. In preparation for doing so, put the sqe copy inside a structure that we can expand. With this pointer added, we can get rid of REQ_F_FREE_SQE, as that is now indicated by whether req->io is NULL or not. No functional changes in this patch.
