From a0c055cfd3a25c37ce95f8febfab9c567db339bb Mon Sep 17 00:00:00 2001 From: Rich Ercolani <214141+rincebrain@users.noreply.github.com> Date: Tue, 1 Jun 2021 14:58:08 -0400 Subject: [PATCH] Remove iov_iter_advance() for iter_write The additional iter advance is incorrect, as copy_from_iter() has already done the right thing. This will result in the following warning being printed to the console as of the 5.12 kernel. Attempted to advance past end of bvec iter This change should have been included with #11378 when a similar change was made on the read side.
