Head SHA1: 8d4e21bd4cca8013d2c6f55d42df85838d4ebce6
Masami Hiramatsu (Google) (3):
function_graph: Handle tail calls for stack unwinding
function_graph: Use a simple LRU for fgraph_array index number
ftrace: Add multiple fgraph storage selftest
Steven Rostedt (Google) (9):
ftrace: Add subops logic to allow one ops to manage many
ftrace: Allow subops filtering to be modified
function_graph: Add pid tracing back to function graph tracer
function_graph: Use for_each_set_bit() in __ftrace_return_to_handler()
function_graph: Use bitmask to loop on fgraph entry
function_graph: Use static_call and branch to optimize entry function
function_graph: Use static_call and branch to optimize return function
selftests/ftrace: Add function_graph tracer to func-filter-pid test
selftests/ftrace: Add fgraph-multi.tc test
Steven Rostedt (VMware) (15):
function_graph: Convert ret_stack to a series of longs
fgraph: Use BUILD_BUG_ON() to make sure we have structures divisible by long
function_graph: Add an array structure that will allow multiple callbacks
function_graph: Allow multiple users to attach to function graph
function_graph: Remove logic around ftrace_graph_entry and return
ftrace/function_graph: Pass fgraph_ops to function graph callbacks
ftrace: Allow function_graph tracer to be enabled in instances
ftrace: Allow ftrace startup flags to exist without dynamic ftrace
function_graph: Have the instances use their own ftrace_ops for filtering
function_graph: Add "task variables" per task for fgraph_ops
function_graph: Move set_graph_function tests to shadow stack global var
function_graph: Move graph depth stored data to shadow stack global var
function_graph: Move graph notrace bit to shadow stack global var
function_graph: Implement fgraph_reserve_data() and fgraph_retrieve_data()
function_graph: Add selftest for passing local variables
