[PATCH AUTOSEL 4.14 12/28] selftests: kmod: fix handling test numbers above 9

by Sasha Levin

From: Eric Biggers <ebiggers(a)google.com> [ Upstream commit 6d573a07528308eb77ec072c010819c359bebf6e ] get_test_count() and get_test_enabled() were broken for test numbers above 9 due to awk interpreting a field specification like '$0010' as octal rather than decimal.

[PATCH AUTOSEL 4.19 44/47] tracing/selftests: Turn off timeout setting

by Sasha Levin

From: "Steven Rostedt (VMware)" <rostedt(a)goodmis.org> [ Upstream commit b43e78f65b1d35fd3e13c7b23f9b64ea83c9ad3a ] As the ftrace selftests can run for a long period of time, disable the timeout that the general selftests have. If a selftest hangs, then it probably means the machine will hang too.
