函数名称:Fast lookup failed, do it the slow way
函数原型:static struct dentry *__lookup_slow(const struct qstr *name, struct dentry *dir, unsigned int flags)
返回类型:struct dentry
参数:
类型 | 参数 | 名称 |
---|---|---|
const struct qstr * | name | |
struct dentry * | dir | |
unsigned int | flags |
1647 | 如果此条件成立可能性小(为编译器优化)(IS_DEADDIR(inode))则返回:错误号 |
1649 | again : |
1650 | dentry等于d_alloc_parallel(dir, name, & wq) |
1653 | 如果此条件成立可能性小(为编译器优化)(!d_in_lookup(dentry))则 |
1654 | error等于d_revalidate(dentry, flags) |
1655 | 如果此条件成立可能性小(为编译器优化)(error <= 0)则 |
1664 | 否则 |
1666 | d_lookup_done(dentry) |
1667 | 如果此条件成立可能性小(为编译器优化)(old)则 |
1672 | 返回:dentry |
