Summary

When using cached attributes, we must update a file's atime during
close, if it has been read since the last attribute refresh.

  • Don't update atime if we lack write permissions to the file or if the file system is readonly.
  • If the daemon fails our atime update request for any reason, don't report this as a failure for VOP_CLOSE.
