iget5_locked - obtain an inode from a mounted file system
struct inode * iget5_locked(struct super_block * sb, unsigned long hashval, int (*test) (struct inode *, void *), int (*set) (struct inode *, void *), void * data);
Search for the inode specified by hashval and data in the inode cache, and if present it is return it with an increased reference count. This is a generalized version of iget_locked for file systems where the inode number is not sufficient for unique identification of an inode.
If the inode is not in cache, allocate a new inode and return it locked, hashed, and with the I_NEW flag set. The file system gets to fill it in before unlocking it via unlock_new_inode.
Note both test and set are called with the inode_hash_lock held, so can't sleep.
