Pull tracing updates from Steven Rostedt:
 "The main changes in this release include:

   - Add user space specific memory reading for kprobes

   - Allow kprobes to be executed earlier in boot

  The rest are mostly just various clean ups and small fixes"

ftrace/selftest: Test if set_event/ftrace_pid exists before writing

2019-07-16T19:14:48+00:00

While testing on a very old kernel (3.5), the tests failed because the write
to set_event_pid in the setup code, did not exist. The tests themselves
could pass, but the setup failed causing an error.

Other files test for existance before writing to them. Do the same for
set_event_pid and set_ftrace_pid.

selftests/ftrace: Add user-memory access syntax testcase

2019-05-26T03:04:42+00:00

Add a user-memory access syntax testcase which checks
new user-memory access syntax and ustring type.

selftests/ftrace: Add checkbashisms meta-testcase

2019-05-24T19:38:29+00:00

Add a meta-testcase which tests ftracetest itself with
checkbasisms. This helps us to keep our test script
bashisms clean.

selftests/ftrace: Make a script checkbashisms clean

2019-05-24T19:37:46+00:00

Make kprobe_ftrace.tc checkbashisms clean. Since
"grep function available_tracers" causes an error
on checkbashisms, fix it by explicitly escaping
with double-quotations.

selftests/ftrace: Add tracing/error_log testcase

Add a testcase verifying basic tracing/error_log functionality.

selftests/ftrace: Remove trigger-extended-error-support testcase

2019-04-08T13:22:50+00:00

Error handling has been moved to the common tracing/error_log, so this
test is no longer valid.

selftests/ftrace: Move kprobe/uprobe check_error() to test.d/functions

2019-04-08T13:22:50+00:00

The k/uprobe_sytax_errors test case defines a check_error() function
used to run a command and check the position of the caret in the
output.

This would be useful for other ftrace facilities too, so move it to
test.d/functions for use by anyone.  In the process, rename it to
ftrace_errlog_check() and parametrize it for general use.

selftests/ftrace: Add error_log testcase for probe errors

is correct.
