dmesg of kernel compiled without ses device.

Starting with 11.1R, the ses0 device uses the bus:target:lun of a disk on D=
ELL
R515 server.  The machine has 8 SATA disks that have been configured in a Z=
FS
pool, but now, one of the disks is not seen due to the ses0 device being
enabled and using the mps address of 1:8:0:

<QUANTUM ULTRIUM 5 3085>           at scbus0 target 3 lun 0 (sa0,pass0)
<DELL PV-124T 0085>                at scbus0 target 3 lun 1 (ch0,pass1)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 3 lun 0 (pass2,da0)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 4 lun 0 (pass3,da1)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 5 lun 0 (pass4,da2)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 6 lun 0 (pass5,da3)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 7 lun 0 (pass6,da4)
<DP BACKPLANE 1.10>                at scbus1 target 8 lun 0 (pass7,ses0)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 9 lun 0 (pass8,da5)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 10 lun 0 (pass9,da6)
<TSSTcorp DVD+-RW TS-L633J D150>   at scbus6 target 0 lun 0 (cd0,pass10)

If the kernel is compiled with the ses device removed from the configuratio=
n, a
passthrough device created on boot which also masks the disk at 1:8:0:

<QUANTUM ULTRIUM 5 3085>           at scbus0 target 3 lun 0 (sa0,pass0)
<DELL PV-124T 0085>                at scbus0 target 3 lun 1 (ch0,pass1)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 3 lun 0 (pass2,da0)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 4 lun 0 (pass3,da1)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 5 lun 0 (pass4,da2)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 6 lun 0 (pass5,da3)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 7 lun 0 (pass6,da4)
<DP BACKPLANE 1.10>                at scbus1 target 8 lun 0 (pass7)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 9 lun 0 (pass8,da5)
<ATA Hitachi HUA72202 A3HA>        at scbus1 target 10 lun 0 (pass9,da6)
<TSSTcorp DVD+-RW TS-L633J D150>   at scbus6 target 0 lun 0 (cd0,pass10)

This hardware has used versions 9.0 through 11.0 without this problem.

Dmesg output attached.
