DROP_NLINK(9) The Linux VFS DROP_NLINK(9)
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.
