[dm-devel] git head multipathd core



Here is a tricky one.
Eyeballs wanted !

It happens upon :

# for i in 3 4 5 6;do for j in 1 2;do echo "scsi remove-single-device $i
0 0 $j">/proc/scsi/scsi;done;done
# multipathd -k"show paths"
# for i in 3 4 5 6;do for j in 1 2;do echo "scsi add-single-device $i 0
0 $j">/proc/scsi/scsi;done;done
# multipathd -k"show paths"
SEGV

(replace your HCIL in the above sample)

Here is the core backtrace :

(gdb) bt full
