385 * uppercase version of the same name with the prefix SMB_ removed
386 * for brevity. Although typedefs are not commonly used for
387 * structure definitions in the Linux kernel, their use in the
388 * CIFS standards document, which this code is based on, may
389 * make this one of the cases where typedefs for structures make
390 * sense to improve readability for readers of the standards doc.
391 * Typedefs can always be removed later if they are too distracting
392 * and they are only used for the CIFSs PDUs themselves, not
393 * internal cifs vfs structures

2180 TRANSACTION2 (18 cases)
2181 SMB_SET_FILE_END_OF_FILE_INFO2 SMB_SET_PATH_END_OF_FILE_INFO2
