Subject: [for-next][PATCH 01/15] tracing: Remove redundant IS_ERR() check in trace_pipe_open()
Date: Fri, 22 May 2026 10:35:09 -0400 [thread overview]
Message-ID: <20260522143525.024053404@kernel.org> (raw)
In-Reply-To: 20260522143508.298439732@kernel.org
From: Yash Suthar <yashsuthar983@gmail.com>
in trace_pipe_open() already check the IS_ERR(iter) and return early on
error,so iter after will be valid and it is safe to return 0 at end.
