## Name

drop_nlink — directly drop an inode's link count

## Synopsis

`void drop_nlink (` | struct inode * inode`)`;

## Arguments

`inode`

  inode

## Description

This is a low-level filesystem helper to replace any direct filesystem manipulation of i_nlink. In cases where we are attempting to track writes to the filesystem, a decrement to zero means an imminent write when the file is truncated and actually unlinked on the filesystem.
