函数名称：set_nlink - directly set an inode's link count*@inode: inode*@nlink: new nlink (should be non-zero)* This is a low-level filesystem helper to replace any* direct filesystem manipulation of i_nlink.

函数原型：void set_nlink(struct inode *inode, unsigned int nlink)

返回类型：void

参数：

类型参数名称
struct inode *inode
unsigned intnlink
335  如果非nlink则
336  lear_nlink - directly zero an inode's link count*@inode: inode* This is a low-level filesystem helper to replace any* direct filesystem manipulation of i_nlink. See* drop_nlink() for why we care about i_nlink hitting zero.
337  否则
339  如果i_nlink恒等于0则atomic_long_dec( & s_remove_count)
342  __i_nlink等于nlink
