From fd593511cdfc0b0e38af2eb21c99f5154a1d7acf Mon Sep 17 00:00:00 2001 From: Beau Belgrave Date: Tue, 28 Mar 2023 16:52:09 -0700 Subject: tracing/user_events: Track fork/exec/exit for mm lifetime During tracefs discussions it was decided instead of requiring a mapping within a user-process to track the lifetime of memory descriptors we should hook the appropriate calls. Do this by adding the minimal stubs required for task fork, exec, and exit. Currently this is just a NOP. Future patches will implement these calls fully.
