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.
