ilookup5_nowait: search for an inode in the inode cache

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.
