The change looks good, but I didn't understand the criteria used to do the change. For example, at udpif_stop_threads() you changed from 'size_t' to 'uint32_t', but variable 'i' is not required to be of the same type (marked in line below). However, I could find other similar cases left unchanged. fbl > > Signed-off-by: Mark Gray <mark.d.g...@redhat.com> > --- > ofproto/ofproto-dpif-upcall.c | 24 ++++++++++++------------ > ofproto/ofproto-dpif-upcall.h | 5 +++-- > ofproto/ofproto-provider.h | 2 +- > ofproto/ofproto.c | 2 +- > 4 files changed, 17 insertions(+), 16 deletions(-) > > diff --git a/ofproto/ofproto-dpif-upcall.c b/ofproto/ofproto-dpif-upcall.c > index ccf97266c0b9..88406fea1391 100644 > --- a/ofproto/ofproto-dpif-upcall.c > +++ b/ofproto/ofproto-dpif-upcall.c > @@ -129,10 +129,10 @@ struct udpif { > struct dpif_backer *backer; /* Opaque dpif_backer pointer. */ > > struct handler *handlers; /* Upcall handlers. */ > - size_t n_handlers; > + uint32_t n_handlers; > > struct revalidator *revalidators; /* Flow revalidators. */ > - size_t n_revalidators; > + uint32_t n_revalidators; > > struct latch exit_latch; /* Tells child threads to exit. */ > > @@ -335,8 +335,8 @@ static int process_upcall(struct udpif *, struct upcall *, > struct ofpbuf *odp_actions, struct flow_wildcards > *); > static void handle_upcalls(struct udpif *, struct upcall *, size_t > n_upcalls); > static void udpif_stop_threads(struct udpif *, bool delete_flows); > -static void udpif_start_threads(struct udpif *, size_t n_handlers, > - size_t n_revalidators); > +static void udpif_start_threads(struct udpif *, uint32_t n_handlers, > + uint32_t n_revalidators); > static void udpif_pause_revalidators(struct udpif *); > static void udpif_resume_revalidators(struct udpif *); > static void *udpif_upcall_handler(void *); > @@ -522,7 +522,7 @@ static void > udpif_stop_threads(struct udpif *udpif, bool delete_flows) > { > if (udpif && (udpif->n_handlers != 0 || udpif->n_revalidators != 0)) { > - size_t i; > + uint32_t i; ^^^^^^^^^^^^^^^^^^^^^^^^ > > /* Tell the threads to exit. */ > latch_set(&udpif->exit_latch); > @@ -562,8 +562,8 @@ udpif_stop_threads(struct udpif *udpif, bool delete_flows) > > /* Starts the handler and revalidator threads. */ > static void > -udpif_start_threads(struct udpif *udpif, size_t n_handlers_, > - size_t n_revalidators_) > +udpif_start_threads(struct udpif *udpif, uint32_t n_handlers_, > + uint32_t n_revalidators_) > { > if (udpif && n_handlers_ && n_revalidators_) { > /* Creating a thread can take a significant amount of time on some > @@ -574,7 +574,7 @@ udpif_start_threads(struct udpif *udpif, size_t > n_handlers_, > udpif->n_revalidators = n_revalidators_; > > udpif->handlers = xzalloc(udpif->n_handlers * sizeof > *udpif->handlers); > - for (size_t i = 0; i < udpif->n_handlers; i++) { > + for (uint32_t i = 0; i < udpif->n_handlers; i++) { > struct handler *handler = &udpif->handlers[i]; > > handler->udpif = udpif; > @@ -632,8 +632,8 @@ udpif_resume_revalidators(struct udpif *udpif) > * datapath handle must have packet reception enabled before starting > * threads. */ > void > -udpif_set_threads(struct udpif *udpif, size_t n_handlers_, > - size_t n_revalidators_) > +udpif_set_threads(struct udpif *udpif, uint32_t n_handlers_, > + uint32_t n_revalidators_) > { > ovs_assert(udpif); > ovs_assert(n_handlers_ && n_revalidators_); > @@ -691,8 +691,8 @@ udpif_get_memory_usage(struct udpif *udpif, struct simap > *usage) > void > udpif_flush(struct udpif *udpif) > { > - size_t n_handlers_ = udpif->n_handlers; > - size_t n_revalidators_ = udpif->n_revalidators; > + uint32_t n_handlers_ = udpif->n_handlers; > + uint32_t n_revalidators_ = udpif->n_revalidators; > > udpif_stop_threads(udpif, true); > dpif_flow_flush(udpif->dpif); > diff --git a/ofproto/ofproto-dpif-upcall.h b/ofproto/ofproto-dpif-upcall.h > index 693107ae56c1..b4dfed32046e 100644 > --- a/ofproto/ofproto-dpif-upcall.h > +++ b/ofproto/ofproto-dpif-upcall.h > @@ -16,6 +16,7 @@ > #define OFPROTO_DPIF_UPCALL_H > > #include <stddef.h> > +#include <inttypes.h> > > struct dpif; > struct dpif_backer; > @@ -31,8 +32,8 @@ struct simap; > void udpif_init(void); > struct udpif *udpif_create(struct dpif_backer *, struct dpif *); > void udpif_run(struct udpif *udpif); > -void udpif_set_threads(struct udpif *, size_t n_handlers, > - size_t n_revalidators); > +void udpif_set_threads(struct udpif *, uint32_t n_handlers, > + uint32_t n_revalidators); > void udpif_destroy(struct udpif *); > void udpif_revalidate(struct udpif *); > void udpif_get_memory_usage(struct udpif *, struct simap *usage); > diff --git a/ofproto/ofproto-provider.h b/ofproto/ofproto-provider.h > index 9ad2b71d23eb..57c7d17cb28f 100644 > --- a/ofproto/ofproto-provider.h > +++ b/ofproto/ofproto-provider.h > @@ -534,7 +534,7 @@ extern unsigned ofproto_min_revalidate_pps; > > /* Number of upcall handler and revalidator threads.
