perf record backward recording doesn't work as we expected: it never
overwrite when ring buffer full.
Test:
(Run a busy printing task background like this:
while True:
print 123
send SIGUSR2 to perf to capture snapshot.)
# ./perf record --overwrite -e raw_syscalls:sys_enter -e
perf record backward recording doesn't work as we expected: it never
overwrite when ring buffer full.
Test:
(Run a busy printing task background like this:
while True:
print 123
send SIGUSR2 to perf to capture snapshot.)
# ./perf record --overwrite -e raw_syscalls:sys_enter -e
