FILEMAP_FAULT(9) Memory Management in Linux FILEMAP_FAULT(9)

NAME

filemap_fault - read in file data for page fault handling

SYNOPSIS

int filemap_fault(struct vm_area_struct * vma, struct vm_fault * vmf);

ARGUMENTS

vma
vma in which the fault was taken
vmf
struct vm_fault containing details of the fault

DESCRIPTION

 
filemap_fault is invoked via the vma operations vector for a mapped memory region to read in file data during a page fault.
The goto's are kind of ugly, but this streamlines the normal case of having it in the page cache, and handles the special cases reasonably without having a lot of duplicated code.
