Name:search the inode cache for a matching inode number.* If we find one, then the inode number we are trying to* allocate is not unique and so we should not use it.* Returns 1 if the inode number is unique, 0 if it is not.
Proto:static int test_inode_iunique(struct super_block *sb, unsigned long ino)
Type:int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct super_block * | sb | |
| unsigned long | ino |
| 1242 | b = inode_hashtable + hash(sb, ino) |
| 1245 | spin_lock( & inode_hash_lock) |
| 1247 | If Stat data, not accessed from path walking == ino && i_sb == sb Then |
| 1248 | spin_unlock( & inode_hash_lock) |
| 1249 | Return 0 |
| 1252 | spin_unlock( & inode_hash_lock) |
| 1254 | Return 1 |
