#     Merge tag 'trace-v5.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
#     
#     Pull tracing fixes from Steven Rostedt:
#     
#      - Fix bootconfig causing kernels to fail with CONFIG_BLK_DEV_RAM
#        enabled
#     
#      - Fix allocation leaks in bootconfig tool
#     
#      - Fix a double initialization of a variable
#     
#      - Fix API bootconfig usage from kprobe boot time events
#     
#      - Reject NULL location for kprobes
#     
#      - Fix crash caused by preempt delay module not cleaning up kthread
#        correctly
#     
#      - Add vmalloc_sync_mappings() to prevent x86_64 page faults from
#        recursively faulting from tracing page faults
#     
#      - Fix comment in gpu/trace kerneldoc header
#     
#      - Fix documentation of how to create a trace event class
#     
#      - Make the local tracing_snapshot_instance_cond() function static
