    NFS: More fine grained attribute tracking · 16e14375
    Trond Myklebust 提交于
    Currently, if the NFS_INO_INVALID_ATTR flag is set, for instance by
    a call to nfs_post_op_update_inode_locked(), then it will not be cleared
    until all the attributes have been revalidated. This means, for instance,
    that NFSv4 writes will always force a full attribute revalidation.
    
    Track the ctime, mtime, size and change attribute separately from the
    other attributes so that we can have nfs_post_op_update_inode_locked()
    set them correctly, and later have the cache consistency bitmask be
    able to clear them.
