Are you able to convert zfs_ioc_pool_create+0x3c into line number?

I use the following script for i386/amd64:

#!/bin/sh

if [ $# -ne 2 ]; then
        echo "usage: `basename $0` kernel function+offset" >/dev/stderr
        exit 1
fi

kern=$1
func=`echo $2 | awk -F+ '{print $1}'`
off=`echo $2 | awk -F+ '{print $2}'`

objdump -d ${kern} | \
	egrep '^[0-9a-f]{8,16} <'${func}'>' | \
	awk '{printf("0x%s\n", $1)}' | \
	xargs -J ADDR printf "%u + %u\n" ADDR $off | \
	bc | \
	xargs printf "0x%x\n" | \
	xargs addr2line -e ${kern}


And:

	fa2line.sh /boot/kernel/zfs.ko.symbols zfs_ioc_pool_create+0x3c
