Protect bpf_token_show_fdinfo with CONFIG_PROC_FS check, otherwise
it will compile error if CONFIG_PROC_FS is not set.
On bpt-next/master, I don't see compile error with
CONFIG_BPF_SYSCALL=y
...
# CONFIG_PROC_FS is not set
Are you testing with a different tree/branch?
Thanks,
Song

Hi Song,
I try it, it seems that i had some misunderstandings before about
CONFIG_PROC_FS, and the description in the changelog is not quite
correct. Please ignore this patch, and i will resend it. Just to follow
the pattern used with other *_show_fdinfo functions and only define
bpf_token_show_fdinfo when CONFIG_PROC_FS is set. Thank you for your
reminder.
