Analyze and fix the following issue in the Linux kernel code: NFS: Remove redundant check in nfs_check_verifier()
Problem Details: The check for nfs_attribute_timeout(dir) in nfs_check_verifier is redundant: nfs_lookup_revalidate() will already call nfs_revalidate_inode() on the parent dir when necessary. The only case where this is not done is the case of a negative dentry. Fix this case by moving up the revalidation code. Sign...

Problem Details: Commit 6fe6900e1e5b6fa9e5c59aa5061f244fe3f467e2 introduced a nasty bug in read_cache_page_async(). It added a "mark_page_accessed(page)" at the final return path in read_cache_page_async(). But in error cases, 'page' holds the error code, and you can't mark it accessed.
