selftests/ftrace: Fix unique symbol check in kprobe_non_uniq_symbol.tcgrafted
The current regex also matches symbols in modules, which makes the test fail on s390 where name_show is present only once in the kernel, but also multiple times in modules: 000001b1401cdc20 t name_show 000001b0c05e6c40 t name_show [mdev] 000001b0c0495f30 t name_show [i2c_core] Fix this by changing the regular expression to only match the function name.

+config JBD2
+ tristate
+ select CRC32
+ help
+ This is a generic journaling layer for block devices that support
+ both 32-bit and 64-bit block numbers. It is currently used by
+ the ext4 and OCFS2 filesystems, but it could also be used to add
+ journal support to other file systems or block devices such
+ as RAID or LVM.
+
+ If you are using ext4 or OCFS2, you need to say Y here.
+ If you are not using ext4 or OCFS2 then you will
+ probably want to say N.
+
+ To compile this device as a module, choose M here. The module will be
+ called jbd2. If you are compiling ext4 or OCFS2 into the kernel,
+ you cannot compile this code as a module.
+
+config JBD2_DEBUG
+ bool "JBD2 (ext4) debugging support"
+ depends on JBD2
+ help
+ If you are using the ext4 journaled file system (or
+ potentially any other filesystem/device using JBD2), this option
+ allows you to enable debugging output while the system is running,
+ in order to help track down any problems you are having.
+ By default, the debugging output will be turned off.
+
+ If you select Y here, then you will be able to turn on debugging
+ with "echo N > /sys/module/jbd2/parameters/jbd2_debug", where N is a
+ number between 1 and 5. The higher the number, the more debugging
+ output is generated. To turn debugging off again, do
+ "echo 0 > /sys/module/jbd2/parameters/jbd2_debug".
