Subject[PATCH 01/27] perf tests: Check that complex event name is parsed correctly
Date
From: Alexey Budankov <alexey.budankov@linux.intel.com>

Extend regression testing to cover case of complex event names enabled
by the cset f92da71280fb ("perf record: Enable arbitrary event names
thru name= modifier").

Testing it:

# perf test
1: vmlinux symtab matches kallsyms : Skip
2: Detect openat syscall event : Ok
3: Detect openat syscall event on all cpus : Ok
4: Read samples using the mmap interface : Ok
5: Test data source output : Ok
6: Parse event definition strings : Ok <===!
7: Simple expression parser : Ok
...

Committer testing:

# perf test "event definition"
6: Parse event definition strings : Ok
# perf test -v 6 2> /tmp/before
# perf test -v 6 2> /tmp/after
# diff -u /tmp/before /tmp/after
