Browse Source 
Running shellcheck -S on probe_vfs_getname.sh, throws below warnings:

Before fix:

$ shellcheck -S warning trace+probe_vfs_getname.sh

	In trace+probe_vfs_getname.sh line 13:
	. $(dirname $0)/lib/probe.sh
	  ^-----------^ SC2046 (warning): Quote this to prevent word splitting.

	In trace+probe_vfs_getname.sh line 18:
	. $(dirname $0)/lib/probe_vfs_getname.sh
	  ^-----------^ SC2046 (warning): Quote this to prevent word splitting.

	In trace+probe_vfs_getname.sh line 21:
		evts=$(echo $(perf list syscalls:sys_enter_open* 2>/dev/null | grep -E 'open(at)? ' | sed -r 's/.*sys_enter_([a-z]+) +\[.*$/\1/') | sed 's/ /,/')
		            ^-- SC2046 (warning): Quote this to prevent word splitting.

Fix the shellcheck warnings by adding quotes to prevent word splitting.
