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 <jrdr.linux@gmail.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Matthew Wilcox <mawilcox@microsoft.com>
