inode_set_max_iversion

函数名称：de_set_max_iversion_raw - update i_version new value is larger*@inode: inode to set*@val: new i_version to set* Some self-managed filesystems (e.g Ceph) will only update the i_version* value if the new value is larger than the one we already have.

函数原型：static inline void inode_set_max_iversion_raw(struct inode *inode, u64 val)

返回类型：void

参数：

类型	参数	名称
struct inode *	inode
u64	val

cur等于de_peek_iversion_raw - grab a "raw" iversion value*@inode: inode from which i_version should be read* Grab a "raw" inode->i_version value and return it. The i_version is not* flagged or converted in any way. This is mostly used to access a self-managed

129

循环

130

如果cur大于val则退出

132

old等于atomic64_cmpxchg( & i_version, cur, val)

133

如果此条件成立可能性大(为编译器优化)(old == cur)则退出

135

cur等于old
