ILOOKUP5(9) The Linux VFS ILOOKUP5(9)
NAME
ilookup5 - search for an inode in the inode cache
SYNOPSIS
struct inode * ilookup5(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
ilookup5 uses ifind to search for the inode specified by hashval and data in the inode cache. This is a generalized version of ilookup for
file systems where the inode number is not sufficient for unique identification of an inode.
If the inode is in the cache, the inode lock is waited upon and the inode is returned with an incremented reference count.
Otherwise NULL is returned.
Note, test is called with the inode_lock held, so can't sleep.
