Subject[PATCH] x86/kprobes: Remove unnecessary extern keyword
Sparse reports a warning at arch_unoptimize_kprobes()

warning: function "arch_unoptimize_kprobes"
with external linkage has definition

The reason is the function is already declared in the header file
as extern

Remove unnecessary "extern" keyword
