Some messages printed related to a WARN_ON(1) were printed using
KERN_NOTICE. Use KERN_WARNING or ext4_warning() instead so that
context related to the WARN_ON() is printed at the same printk warning
level (and log files, etc.)

The current code in pnfs_destroy_all_layouts() assumes that removing
the layout from the server->layouts list is sufficient to make it
invisible to other processes. This ignores the fact that most
users access the layout through the nfs_inode->layout...
There is further breakage due to lack of reference counting of the
layouts, meaning that the whole thing Oopses at the drop of a hat.
The code in initiate_bulk_draining() is almost correct, and can be
used as a model for pnfs_destroy_all_layouts(), so move that
code to pnfs.c, and refactor the code to allow us to choose between
a single filesystem bulk recall, and a recall of all layouts.
Also note that initiate_bulk_draining() currently calls iput() while
holding locks. Fix that too.

This virtual xattr will only appear when there is a dir layout policy
set on the directory. It can be set via setxattr and removed via
removexattr (implemented by the MDS).

Implement a new method to generate the ceph.file.layout vxattr using

Only include vxattrs in the result if they are not hidden and exist
(as determined by the exists_cb callback).
Note that the buffer size we return when 0 is passed in always includes
vxattrs that *might* exist, forming an upper bound.

The cifs protocol has a 64bit space for uids and gids, while linux
only supports a 32bit space today. Instead of silently truncating
64bit cifs ids, replace cifs ids that do not fit in the 32bit linux
id space with the default uid and gids for the cifs mount.
