ilookup5 — search for an inode in the inode cache

int (*)(struct inode *, void *) testcallback used for comparisons between inodes
void * data
opaque data pointer to pass to test
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.
