Hello, Atish.

The above series won't compile with CONFIG_BPF_SYSCALL set:

linux/kernel/events/core.c:9912:18: error: assignment to 
'bpf_user_pt_regs_t *' {aka 'struct user_regs_struct *'} 
from incompatible pointer type 'struct pt_regs *' 
[-Werror=incompatible-pointer-types]
 9912 |         ctx.regs = perf_arch_bpf_user_pt_regs(regs);

Just informing you - hope this is helpful.

Yours,
Nikita Shubin
