Subject: threads scsi_eh_  and scsi_tmf_ don't die when ib_srp reconnect

Hello list!


I was faced with the following problem:

Im exported to compute-node scsi disks through ib_srp from storages. And 
if reconnect occurs for any reason, eg

"[1201117.626498] scsi host62: ib_srp: REJ received
[1201117.626507] scsi host62: ib_srp: SRP LOGIN from 
fe80:0000:0000:0000:0002:c903:0009:1796 to 
fe80:0000:0000:0000:0002:c903:0009:c1a0 REJECTED, reason 0x00010001
[1201117.626656] scsi host62: ib_srp: Connection 0/8 failed"

i find threads in output ps:
"root     28047  0.0  0.0      0     0 ?        S    18:04   0:00 
[scsi_eh_62]
root     28048  0.0  0.0      0     0 ?        S<   18:04   0:00 
[scsi_tmf_62]"

Each reconnect generates two thread, which do not die.

kernel version 3.19.1
