Subject: [PATCH v1 1/9] mm/mmap: Move exit_mmap() trace point
Date: Tue, 9 Sep 2025 15:09:37 -0400 [thread overview]
Message-ID: <20250909190945.1030905-2-Liam.Howlett@oracle.com> (raw)
In-Reply-To: <20250909190945.1030905-1-Liam.Howlett@oracle.com>
Move the trace point later in the function so that it is not skipped in
the event of a failed fork.
