Hi Masami,

I think this worked at some point?

[root@jouet acme]# perf probe -F | tail
zswap_frontswap_init
zswap_frontswap_invalidate_area
zswap_frontswap_invalidate_page
zswap_frontswap_load
zswap_frontswap_store
zswap_pool_create
zswap_pool_current
zswap_update_total_size
zswap_writeback_entry
zswap_zpool_param_set
[root@jouet acme]# perf probe -F rt_sp*
no symbols found in [kernel.kallsyms], maybe install a debug package?
Failed to load symbols in kernel
[root@jouet acme]# perf probe -F rt_sp\*
no symbols found in [kernel.kallsyms], maybe install a debug package?
Failed to load symbols in kernel
[root@jouet acme]#


I.e. the second message is misleading :-\
