ILOOKUP5_NOWAIT(9) The Linux VFS ILOOKUP5_NOWAIT(9)NAMEilookup5_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.
