Subject: [PATCH V10 06/12] io_uring: rename io_mapped_buf->ubuf as io_mapped_buf->addr
Date: Thu,  7 Nov 2024 19:01:39 +0800	[thread overview]
Message-ID: <20241107110149.890530-7-ming.lei@redhat.com> (raw)
In-Reply-To: <20241107110149.890530-1-ming.lei@redhat.com>

->addr of `io_mapped_buf` stores the start address of userspace fixed
buffer. `io_mapped_buf` will be extended for covering kernel buffer,
so rename ->ubuf as ->addr.
