svn commit: r187654 - head/sys/kern

[John Baldwin]

New Revision: 187654
URL: http://svn.freebsd.org/changeset/base/187654

Log:
  Tweak the wording for vfs_mark_atime() since the I/O it is avoiding by not
  updating va_atime via VOP_SETATTR() isn't always synchronous.  For some
  filesystems it is asynchronous.
