Subject: [PATCH 5/6] perf mem: Add -s/--sort option
So that users can set the sort key manually as they want.
$ perf mem report -s
Error: switch `s' requires a value
Usage: perf mem report [<options>]
-s, --sort <key[,key2...]>
sort by key(s): overhead overhead_sys overhead_us overhead_guest_sys
overhead_guest_us overhead_children sample period
weight1 weight2 weight3 ins_lat retire_lat p_stage_cyc
pid comm dso symbol parent cpu socket srcline srcfile
local_weight weight transaction trace symbol_size
dso_size cgroup cgroup_id ipc_null time code_page_size
local_ins_lat ins_lat local_p_stage_cyc p_stage_cyc
addr local_retire_lat retire_lat simd type typeoff
symoff symbol_daddr dso_daddr locked tlb mem snoop
dcacheline symbol_iaddr phys_daddr data_page_size
blocked
