f_next() looks overcomplicated, and it is not strictly correct
even if this doesn't matter.
Say, FORMAT_FIELD_SEPERATOR should not return NULL (means EOF)
if trace_get_fields() returns an empty list, we should simply
advance to FORMAT_PRINTFMT as we do when we find the end of list.
1. Change f_ne
Finally change f_start() to take event_mutex and verify i_private,
f_stop() drops this lock. This closes the races with event_remove.
Note: the usage of event_mutex is sub-optimal but simple, we can
change this later.

Hi, I have a patch (following) that modifies handling of APIC id tables,
trading a small amount of space in the (NR_CPUS - nr_cpu_ids) >> 0 case for
faster accesses and slightly better cache layout (as APIC ids are mostly used
cross-cpu.) I'm not an APIC expert so I'd appreciate some eyes on this,

Honestly, I do not know what the changelog can say to explain
this patch except "make the code simpler/cleaner".
To simplify the review, please see f_next/f_start with

At present, the page fault path for hugepages is serialized by a
single mutex. This is used to avoid spurious out-of-memory conditions
when the hugepage pool is fully utilized (two processes or threads can

Actually, it *not* clear. Without drawing fine distinctions about
