If anyone has any objections, please let me know. ------------------ From: Sasha Levin <sasha.levin@...cle.com> commit ffd8d101a3a7d3f2e79deee1e342801703b6dc70 upstream. Commit "fs: add link restriction audit reporting" has added auditing of failed attempts to follow symlinks. Unfortunately, the auditing was being done after the struct path structure was released earlier.
