7

SYNOPSIS

10

ARGUMENTS

12       vma
13           vma in which the fault was taken
14
15       vmf
16           struct vm_fault containing details of the fault
17

DESCRIPTION

19       filemap_fault is invoked via the vma operations vector for a mapped
20       memory region to read in file data during a page fault.
21
22       The goto's are kind of ugly, but this streamlines the normal case of
23       having it in the page cache, and handles the special cases reasonably
24       without having a lot of duplicated code.
