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
