9 struct inode * ilookup5(struct super_block * sb, unsigned long hashval,
10 int (*test) (struct inode *, void *),
11 void * data);
12
14 sb
15 super block of file system to search
16
17 hashval
18 hash value (usually inode number) to search for
19
20 test
21 callback used for comparisons between inodes
22
23 data
24 opaque data pointer to pass to test
25
27 Search for the inode specified by hashval and data in the inode cache,
28 and if the inode is in the cache, return the inode with an incremented
29 reference count. Waits on I_NEW before returning the inode. returned
30 with an incremented reference count.
31
32 This is a generalized version of ilookup for file systems where the
33 inode number is not sufficient for unique identification of an inode.
34
36 test is called with the inode_hash_lock held, so can't sleep.
