Goldwyn Rodrigues 5e98d49240 Track negative entries v3 ... Track negative dentries by recording the generation number of the parent directory in d_fsdata. The generation number for the parent directory is recorded in the inode_info, which increments every time the lock on the directory is dropped. If the generation number of the parent directory and the negative dentry matches, there is no need to perform the revalidate, else a revalidate is forced. This improves performance in situations where nodes look for the same non-existent file multiple times. Thanks Mark for explaining the DLM sequence.
