52 * Trace include reorganization: split old tasking/Trace.h into five new
53 * files, and move most of them into directories that will be shipped with
54 * GPFS on Linux.  Also change the code in trcid.h files generated by
55 * mktrace to not include AIX specific stuff like direct use of AIX trace
56 * macros.  Change names of all macros in generated code to have a leading
57 * underscore.  As a result of these changes, all trcid.h files had to
58 * be rebuilt.

74   (GPFS_LOCK_xxx_IDX).  To add a new lock class, add both defines and
