Fix wraparound issue with nfsi->cache_change_attribute. If it is found to lie in the future, then update it to lie in the past.

If the fileid of the cached dentry fails to match that returned by the readdir call, then we should also d_drop. Try to take into account the fact that on NFSv4, readdir may return the "mounted_on_fileid" by looking for submounts. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

Make sure that nfs_readdir_lookup() handles negative dentries correctly. If d_lookup() returns a negative dentry, then we need to d_drop() that since readdir shows that it should be positive. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

When a file is being scheduled for deletion by means of the sillyrename mechanism, it makes sense to start out writeback of the dirty data as soon as possible in order to ensure that the delete can occur. Examples of cases where this is an issue include "rm -rf", which will busy-wait until the file is closed, and the sillyrename completes. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>

But keep it as a dprintk The message can be generated in a quite normal situation: If a 'lock' request is interrupted, then the lock client needs to record that the server has the lock, incase it does. When we come the unlock, the server might say it doesn't, even though we think it does (or might) and this generates the message.

NFS: Fix race in nfs_release_page() invalidate_inode_pages2() may find the dirty bit has been set on a page owing to the fact that the page may still be mapped after it was locked. Only after the call to unmap_mapping_range() are we sure that the page can no longer be dirtied. In order to fix this, NFS has hooked the releasepage() method and tries to write the page out between the call to unmap_mapping_range() and the call to remove_mapping(). This, however leads to deadlocks in the page reclaim code, where the page may be locked without holding a reference to the inode or dentry. Fix is to add a new address_space_operation, launder_page(), which will attempt to write out a dirty page without releasing the page lock. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com> Also, the bare SetPageDirty() can skew all sort of accounting leading to other nasties.

We will want to allow nfs_writepage() to distinguish between pages that have been marked as dirty by the VM, and those that have been marked as dirty by nfs_updatepage(). In the former case, the entire page will want to be written out, and so any requests that were pending need to be flushed out first. Signed-off-by: NTrond Myklebust <Trond.Myklebust@netapp.com>
