Comment 2 for bug 1854550

This is a fix for a commit that landed in v4.19, so marking Ubuntu-18.04 Invalid.

    Fixes: 651a013649943 ("scsi: scsi_transport_sas: switch to bsg-lib for SMP passthrough")

While it is a small memory leak, it does appear to be something users would be unlikely to hit or notice, so I don't think it would qualify for SRU - but seems like something we should fix for 20.04.

Also, fix is in linux-next, so marking triaged.
