kprobes: Fix build errors with CONFIG_KRETPROBES=n
Max Filippov reported:
When building kernel with CONFIG_KRETPROBES=n kernel/kprobes.c
compilation fails with the following messages:
kernel/kprobes.c: In function ‘recycle_rp_inst’:
kernel/kprobes.c:1273:32: error: implicit declaration of function
‘get_kretprobe’
kernel/kprobes.c: In function ‘kprobe_flush_task’:
kernel/kprobes.c:1299:35: error: ‘struct task_struct’ has no member
named ‘kretprobe_instances’
This came from the commit d741bf41d7c7 ("kprobes: Remove
kretprobe hash") which introduced get_kretprobe() and
kretprobe_instances member in task_struct when CONFIG_KRETPROBES=y,
but did not make recycle_rp_inst() and kprobe_flush_task()
depending on CONFIG_KRETPORBES.
Since those functions are only used for kretprobe, move those
functions into #ifdef CONFIG_KRETPROBE area.
