USER SCHEDULING LIST ANCHORS USERS IN THE ELIGIBLE AND DORMANT LISTS ARE CHAINED TO EACH OTHER. THE FOLLOWING ANCHORS POINT TO THE FIRST USER ON THE CORRESPONDING LIST. IF THERE IS NO USER IN THE LIST, THE POINTER HAS A VALUE OF ZERO. THE USERS ARE DOUBLE-LINKED VIA VMDQFPNT/VMDQBPNT. Start of x'000' cache line 0000 0 Signed 4 SRMELIST ELIGIBLE LIST ANCHOR 0004 4 Signed 4 SRMMLIST DORMANT LIST ANCHOR The dispatch list is anchored for scheduling purposes by the System VMDBK, which is the first member of the dispatch list. 0008 8 Address 4 * Reserved for IBM use 000C 12 Address 4 SRME1ADD Last user added to E-list, by 0010 16 Address 4 SRME2ADD class.

It did once, but that user dropped from the E-list so the pointer bumped to the next VMDBK.

SRMSCHLK is aligned so the SXLXL is in the cache line by itself. This block is the global lockword for the Scheduler Lock which is the most frequently used spinlock in the system. Keeping this block in a cache line by itself avoids unnecessary cache contention with any other data usage in the SRMBK. The Scheduler Lock SXLXL data structure does not use the old SRMSLOCK name or location to avoid potential problems with any software that may inspect the storage location and misinterpret the data in the block. This way all contents will be zero making it obvious that it is not what they think it is. The SYNBX portion of SRMSLOCK was previously in the next cache line.
