NAME
       ilookup - search for an inode in the inode cache

SYNOPSIS
       struct inode * ilookup(struct super_block * sb, unsigned long ino);

ARGUMENTS
       sb
	   super block of file system to search

       ino
	   inode number to search for

DESCRIPTION
       ilookup uses ifind_fast to search for the inode ino in the inode cache. This is for file systems where the inode number is sufficient for
       unique identification of an inode.

       If the inode is in the cache, the inode is returned with an incremented reference count.

       Otherwise NULL is returned.
