Name
drop_nlink — 
     directly drop an inode's link count
 
Synopsis
| void drop_nlink ( | struct 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.
