If the directory contents change, then we have to accept that the file->f_pos value may shrink if we do a 'search-by-cookie'. In that case, we should turn off the loop detection and let the NFS client try to recover. The patch also fixes a second loop detection bug by ensuring that after turning on the ctx->duped flag, we read at least one new cookie into ctx->dir_cookie before attempting to match with ctx->dup_cookie.

nfs_mark_return_delegation() is usually called without any locking, and so it is not safe to dereference delegation->inode. Since the inode is only used to discover the nfs_client anyway, it makes more sense to have the callers pass a valid pointer to the nfs_server as a parameter.

If the task that initiated the sillyrename ends up being killed by a fatal signal, then it will eventually return back to userspace and end up releasing the i_mutex. d_move however needs to be done while holding the i_mutex. Instead of using d_move here, just unhash the old and new dentries to prevent them from being found by lookups. With this change though, the dentries are now incorrect post-rename and do not reflect the actual name of the file on the server. I'm proceeding under the assumption that since they are unhashed that this isn't really a problem. In order for the sillydelete to still work though, the dname must be copied earlier when setting up the sillydelete info, and the name must be recopied if the sillydelete info has to be moved to a new dentry.

Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

This converts everybody to handle SEEK_HOLE/SEEK_DATA properly. In some cases we just return -EINVAL, in others we do the normal generic thing, and in others we're simply making sure that the properly due-dilligence is done. For example in NFS/CIFS we need to make sure the file size is update properly for the SEEK_HOLE and SEEK_DATA case, but since it calls the generic llseek stuff itself that is all we have to do.

If we're writing back data, and the FLUSH_STABLE flag is set, then we always want to use NFS_FILE_SYNC, since we're always in a situation where we're doing page reclaim, and so we want to free up the page as quickly as possible. If we're in the FLUSH_COND_STABLE case, then we either want to use another unstable write (if we have to do a commit anyway) or again, we want to use NFS_FILE_SYNC because we know that we have no more pages to write out.
