Some headers are not necessary, so let's remove them to do some cleaning.

Please use Rule #1 from Documentation/process/submit-checklist.rst: 1) If you use a facility then #include the file that defines/declares that facility. Don't depend on other header files pulling in ones that you use. so just because it will compile without these headers being explictly #included does not mean that you should remove them.> --- > v3: > - avoided to remove some headers with structures and functions directly > used (device.h, slab.h, virtio_byteorder.h)[Jason] > --- > drivers/vdpa/vdpa_sim/vdpa_sim.c | 10 ---------- > 1 file changed, 10 deletions(-) > > diff --git a/drivers/vdpa/vdpa_sim/vdpa_sim.c b/drivers/vdpa/vdpa_sim/vdpa_sim.c > index 6a90fdb9cbfc..b08f28d20d8d 100644 > --- a/drivers/vdpa/vdpa_sim/vdpa_sim.c > +++ b/drivers/vdpa/vdpa_sim/vdpa_sim.c > @@ -7,20 +7,10 @@ > * > */ > > -#include <linux/init.h>above is used by __init and __exit.> #include <linux/module.h> > #include <linux/device.h> > -#include <linux/kernel.h> > -#include <linux/fs.h> > -#include <linux/poll.h>Looks OK to remove poll.h.> #include <linux/slab.h> > -#include <linux/sched.h>Might be OK for sched.h.> -#include <linux/wait.h>Might be OK for wait.h.> -#include <linux/uuid.h> > -#include <linux/iommu.h> > #include <linux/dma-map-ops.h> > -#include <linux/sysfs.h> > -#include <linux/file.h> > #include <linux/etherdevice.h> > #include <linux/vringh.h> > #include <linux/vdpa.h> >I didn't check the others. -- ~Randy
