[PATCH AUTOSEL 4.19 24/84] selftests/ftrace: Fix multiple kprobe testcase

by Sasha Levin

From: Masami Hiramatsu <mhiramat(a)kernel.org> [ Upstream commit 5cc6c8d4a99d0ee4d5466498e258e593df1d3eb6 ] Fix multiple kprobe event testcase to work it correctly. There are 2 bugfixes. - Since `wc -l FILE` returns not only line number but also FILE filename, following "if" statement always failed. Fix this bug by replacing it with 'cat FILE | wc -l' - Since "while do-done loop" block with pipeline becomes a subshell, $N local variable is not update outside of the loop.
