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
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.
Otherwise NULL is returned.
Note, test
is called with the inode_lock held, so can't sleep.
