NAME

vmtruncate - unmap mappings lqfreedrq by truncate syscall

SYNOPSIS

int vmtruncate(struct inode * inode, loff_t offset);

ARGUMENTS

inode

inode of the file used

offset

DESCRIPTION

NOTE! We have to be ready to update the memory sharing between the file and the memory map for a potential last incomplete page. Ugly, but necessary.

This function is deprecated and simple_setsize or truncate_pagecache should be used instead.
