Merge tag 'trace-v4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt:
"Three minor updates
- Use the new GFP_RETRY_MAYFAIL to be more aggressive in allocating
memory for the ring buffer without causing OOMs
- Fix a memory leak in adding and removing instances
- Add __rcu annotation to be able to debug RCU usage of function
tracing a bit better"
* tag 'trace-v4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
trace: fix the errors caused by incompatible type of RCU variables
tracing: Fix kmemleak in instance_rmdir
tracing/ring_buffer: Try harder to allocate
