ILOOKUP5_NOWAIT(9)                        The Linux VFS                        ILOOKUP5_NOWAIT(9)



NAME
       ilookup5_nowait - search for an inode in the inode cache

SYNOPSIS
       struct inode * ilookup5_nowait(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
       Search for the inode specified by hashval and data in the inode cache. If the inode is in
       the cache, the inode is returned with an incremented reference count.

NOTE
       I_NEW is not waited upon so you have to be very careful what you do with the returned
       inode. You probably should be using ilookup5 instead.

       Note2: test is called with the inode_hash_lock held, so can't sleep.
