Proto:struct dentry *lookup_one_len_unlocked(const char *name, struct dentry *base, int len)
Type:struct dentry
Parameter:
| Type | Parameter | Name |

| const char * | name | |
| struct dentry * | base | |
| int | len |
| 2553 | err = lookup_one_len_common(name, base, len, & this) |
| 2557 | ret = This looks up the name in dcache and possibly revalidates the found dentry.* NULL is returned if the dentry does not exist in the cache. |
| 2558 | If Not ret Then ret = lookup_slow( & this, base, 0) |
| 2560 | Return ret |
