From 71fe989961374ae55863c5da527bcf45be020834 Mon Sep 17 00:00:00 2001 From: Souptick Joarder Date: Sun, 13 May 2018 16:01:49 -0400 Subject: fs: ext4: add new return type 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 Signed-off-by: Theodore Ts'o Reviewed-by: Matthew Wilcox --- fs/ext4/file.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'fs/ext4') diff --git a/fs/ext4/file.c b/fs/ext4/file.c index fb6f023622fe..655d1c7bc614 100644 --- a/fs/ext4/file.c +++ b/fs/ext4/file.c @@ -277,10 +277,11 @@ out: } #ifdef CONFIG_FS_DAX -static int ext4_dax_huge_fault(struct vm_fault *vmf, +static vm_fault_t ext4_dax_huge_fault(struct vm_fault *vmf, enum page_entry_size pe_size) { - int result, error = 0; + int error = 0; + vm_fault_t result; int retries = 0; handle_t *handle = NULL; struct inode *inode = file_inode(vmf->vma->vm_file); @@ -335,7 +336,7 @@ retry: return result; } -static int ext4_dax_fault(struct vm_fault *vmf) +static vm_fault_t ext4_dax_fault(struct vm_fault *vmf) { return ext4_dax_huge_fault(vmf, PE_SIZE_PTE); } -- cgit v1.2.3
