ilookup5_nowait - search for an inode in the inode cache
struct inode * ilookup5_nowait (struct super_block * sb,
unsigned long hashval,
int (*test) <funcparams>struct inode *, void *</funcparams>,
void * data);
sb super block of file system to search
hash value (usually inode number) to search for
test callback used for comparisons between inodes
data opaque data pointer to pass to test
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 is returned with an incremented
reference count. Note, the inode lock 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.
Otherwise NULL is returned.
Note, test is called with the inode_lock held, so can’t sleep.
