Author: rwatson Date: Tue Jul 5 16:37:01 2016 New Revision: 302345 URL: https://svnweb.freebsd.org/changeset/base/302345 Log: Call audit hooks to capture vnode attributes for three file-descriptor method implementations: fstat(2), close(2), and poll(2). This change synchronises auditing here with similar auditing for VFS-specific system calls such as stat(2) that audit more complete vnode information.
