From 6c2590914cffa9212874da5c1eddfcfe6553bda6 Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Thu, 10 May 2018 19:12:04 +0530 Subject: gpu: drm: drm_vm: Adding new typedef vm_fault_t Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. commit 1c8f422059ae ("mm: change return type to vm_fault_t") Signed-off-by: Souptick Joarder Reviewed-by: Matthew Wilcox Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20180510134203.GA25166@jordon-HP-15-Notebook-PC --- drivers/gpu/drm/drm_vm.c | 10 +++++----- 1 file changed, 5 insertions(+), 5 deletions(-) (limited to 'drivers/gpu/drm/drm_vm.c') diff --git a/drivers/gpu/drm/drm_vm.c b/drivers/gpu/drm/drm_vm.c index 2660543ad86a..c3301046dfaa 100644 --- a/drivers/gpu/drm/drm_vm.c +++ b/drivers/gpu/drm/drm_vm.c @@ -100,7 +100,7 @@ static pgprot_t drm_dma_prot(uint32_t map_type, struct vm_area_struct *vma) * map, get the page, increment the use count and return it. */ #if IS_ENABLED(CONFIG_AGP) -static int drm_vm_fault(struct vm_fault *vmf) +static vm_fault_t drm_vm_fault(struct vm_fault *vmf) { struct vm_area_struct *vma = vmf->vma; struct drm_file *priv = vma->vm_file->private_data; @@ -173,7 +173,7 @@ vm_fault_error: return VM_FAULT_SIGBUS; /* Disallow mremap */ } #else -static int drm_vm_fault(struct vm_fault *vmf) +static vm_fault_t drm_vm_fault(struct vm_fault *vmf) { return VM_FAULT_SIGBUS; } @@ -189,7 +189,7 @@ static int drm_vm_fault(struct vm_fault *vmf) * Get the mapping, find the real physical page to map, get the page, and * return it. */ -static int drm_vm_shm_fault(struct vm_fault *vmf) +static vm_fault_t drm_vm_shm_fault(struct vm_fault *vmf) { struct vm_area_struct *vma = vmf->vma; struct drm_local_map *map = vma->vm_private_data; @@ -291,7 +291,7 @@ static void drm_vm_shm_close(struct vm_area_struct *vma) * * Determine the page number from the page offset and get it from drm_device_dma::pagelist. */ -static int drm_vm_dma_fault(struct vm_fault *vmf) +static vm_fault_t drm_vm_dma_fault(struct vm_fault *vmf) { struct vm_area_struct *vma = vmf->vma; struct drm_file *priv = vma->vm_file->private_data; @@ -326,7 +326,7 @@ static int drm_vm_dma_fault(struct vm_fault *vmf) * * Determine the map offset from the page offset and get it from drm_sg_mem::pagelist. */ -static int drm_vm_sg_fault(struct vm_fault *vmf) +static vm_fault_t drm_vm_sg_fault(struct vm_fault *vmf) { struct vm_area_struct *vma = vmf->vma; struct drm_local_map *map = vma->vm_private_data; -- cgit v1.2.3-59-g8ed1b
