1364  again :
1365  inode = lookup5_nowait - search for an inode in the inode cache*@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
1366  If inode Then
1367  writeback.h requires fs.h; it, too, is not included from here.
1368  If Value for the false possibility is greater at compile time(inode_unhashed(inode)) Then
1369  put an inode
1370  Go to again
