NAME¶

iget5_locked - obtain an inode from a mounted file system

SYNOPSIS¶

struct inode * iget5_locked(struct super_block * sb, unsigned long hashval, int (*test) (struct inode *, void *), int (*set) (struct inode *, void *), void * data);

ARGUMENTS¶

sb

hashval

test

set

data

DESCRIPTION¶

iget5_locked uses ifind to search for the inode specified by hashval and data in the inode cache and if present it is returned 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, get_new_inode is called to allocate a new inode and this is returned 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_lock held, so can´t sleep.
