Subject: Re: [PATCH V5 1/3] perf & kvm: Enhance perf to collect KVM guest os statistics from host side
Date: Mon, 19 Apr 2010 20:11:54 +0200 [thread overview]
Message-ID: <20100419181154.GA14631@elte.hu> (raw)
In-Reply-To: <1271655161.2078.603.camel@ymzhang.sh.intel.com>
FYI, i found a few problems that need fixing:
> + unsigned long ip;
> + if (perf_guest_cbs && perf_guest_cbs->is_in_guest())
missing newline.
> + int misc = 0;
> + if (perf_guest_cbs && perf_guest_cbs->is_in_guest()) {
ditto.
> + PERF_RECORD_MISC_GUEST_KERNEL;
> + } else
> + misc |= user_mode(regs) ? PERF_RECORD_MISC_USER :
> + PERF_RECORD_MISC_KERNEL;
- unbalanced curly braces
- missing curly brace for multi-line statement.
- unnecessary line-break due to col80 warning from checkpatch
> +extern struct perf_guest_info_callbacks *perf_guest_cbs;
> +extern int perf_register_guest_info_callbacks(
> + struct perf_guest_info_callbacks *);
> +extern int perf_unregister_guest_info_callbacks(
> + struct perf_guest_info_callbacks *);
- unnecessary line-break due to col80 warning from checkpatch
> +static inline int perf_register_guest_info_callbacks
> +(struct perf_guest_info_callbacks *) {return 0; }
> +static inline int perf_unregister_guest_info_callbacks
> +(struct perf_guest_info_callbacks *) {return 0; }
- invalid C: function parameter needs name even if unused
- missing space after opening curly brace
Please provide delta fixes.
