Merge tag 'trace-v5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull tracing fixes from Steven Rostedt: "Various fixes: - Fix an uninitialized variable - Fix compile bug to bootconfig userspace tool (in tools directory) - Suppress some error messages of bootconfig userspace tool - Remove unneded CONFIG_LIBXBC from bootconfig - Allocate bootconfig xbc_nodes dynamically. To ease complaints about taking up static memory at boot up - Use of parse_args() to parse bootconfig instead of strstr() usage Prevents issues of double quotes containing the interested string - Fix missing ring_buffer_nest_end() on synthetic event error path - Return zero not -EINVAL on soft disabled synthetic event (soft disabling must be the same as hard disabling, which returns zero) - Consolidate synthetic event code (remove duplicate code)" * tag 'trace-v5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Consolidate trace() functions tracing: Don't return -EINVAL when tracing soft disabled synth events tracing: Add missing nest end to synth_event_trace_start() error case tools/bootconfig: Suppress non-error messages bootconfig: Allocate xbc_nodes array dynamically bootconfig: Use parse_args() to find bootconfig and '--' tracing/kprobe: Fix uninitialized variable bug bootconfig: Remove unneeded CONFIG_LIBXBC tools/bootconfig: Fix wrong __VA_ARGS__ usage
