NAME
       ilookup5 - search for an inode in the inode cache

SYNOPSIS
       struct inode * ilookup5(struct super_block * sb, unsigned long hashval, int (*test) (struct inode *, void *), void * data);

ARGUMENTS
       sb
	   super block of file system to search

       hashval
	   hash value (usually inode number) to search for

       test
	   callback used for comparisons between inodes

       data
	   opaque data pointer to pass to test

DESCRIPTION
       Search for the inode specified by hashval and data in the inode cache, and if the inode is in the cache, return the inode with an
       incremented reference count. Waits on I_NEW before returning the inode. returned with an incremented reference count.

       This is a generalized version of ilookup for file systems where the inode number is not sufficient for unique identification of an inode.

NOTE
       test is called with the inode_hash_lock held, so can't sleep.
