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
       ilookup5 uses ifind to search for the inode specified by hashval and data in the inode cache. This is a generalized version of ilookup for
       file systems where the inode number is not sufficient for unique identification of an inode.

       If the inode is in the cache, the inode lock is waited upon and the inode is returned with an incremented reference count.

       Otherwise NULL is returned.

       Note, test is called with the inode_lock held, so can't sleep.
