Subject: [PATCH 2/3] smb: client: get rid of bounds check in SMB2_ioctl_init()
Date: Mon, 18 Nov 2024 12:35:15 -0300 [thread overview]
Message-ID: <20241118153516.48676-2-pc@manguebit.com> (raw)
In-Reply-To: <20241118153516.48676-1-pc@manguebit.com>
smb2_set_next_command() no longer squashes request iovs into a single
iov, so the bounds check can be dropped.
