1392  如果非policy_view_capable - check if viewing policy in at @ns is allowed* Returns: true if viewing policy is allowed* If @ns is NULL then the namespace being viewed is assumed to be the* tasks current namespace.则返回:负EACCES
1395  loaddata等于__aa_get_loaddata - get a reference count to uncounted data reference*@data: reference to get a count on* Returns: pointer to reference OR NULL if race is lost and reference is* being repeated
1396  如果非loaddata则返回:负ENOENT
1400  private等于rawdata_f_data_alloc(he original size of the payload )
1401  如果是错误则
1402  error等于错误
1403  转到:fail_private_alloc
1406  loaddata等于loaddata
1408  error等于deflate_decompress(Pointer to payload. If @compressed_size > 0, then this is the* compressed version of the payload, else it is the uncompressed* version (with the size indicated by @size)., he compressed size of the payload , RAWDATA_F_DATA_BUF(private), he original size of the payload )
1411  如果error则转到:fail_decompress
1414  needed for tty driver, and maybe others 等于private
1415  返回:0
1417  fail_decompress :
1418  rawdata_f_data_free(private)
1419  返回:error
1421  fail_private_alloc :
1422  aa_put_loaddata(loaddata)
1423  返回:error
