Name:de_insert5 - obtain an inode from a mounted file system*@inode: pre-allocated inode to use for insert to cache*@hashval: hash value (usually inode number) to get*@test: callback used for comparisons between inodes*@set: callback used to initialize a new

Proto:struct inode *inode_insert5(struct inode *inode, unsigned long hashval, int (*test)(struct inode *, void *), int (*set)(struct inode *, void *), void *data)
