perf probe: Add variable filter support
Add filters support for available variable list. Default filter is "!__k???tab_*&!__crc_*" for filtering out automatically generated symbols. The format of filter rule is "[!]GLOBPATTERN", so you can use wild cards. If the filter rule starts with '!', matched variables are filter out. e.g.: # perf probe -V schedule --externs --filter=cpu* Available variables at schedule @<schedule+0> cpumask_var_t cpu_callout_mask cpumask_var_t cpu_core_map cpumask_var_t cpu_isolated_map cpumask_var_t cpu_sibling_map int cpu_number long unsigned int* cpu_bit_bitmap ...
