The Lustre filesystem has been in the kernel tree for over 5 years now.
While it has been an endless source of enjoyment for new kernel
developers learning how to do basic codingstyle cleanups, as well as an
semi-entertaining source of bewilderment from the vfs developers any
time they have looked into the codebase to try to figure out how to port
their latest api changes to this filesystem, it has not really moved
forward into the "this is in shape to get out of staging" despite many
half-completed attempts.
And getting code out of staging is the main goal of that portion of the
kernel tree. Code should not stagnate and it feels like having this
code in staging is only causing the development cycle of the filesystem
to take longer than it should. There is a whole separate out-of-tree
copy of this codebase where the developers work on it, and then random
changes are thrown over the wall at staging at some later point in time.
This dual-tree development model has never worked, and the state of this
codebase is proof of that.
So, let's just delete the whole mess. Now the lustre developers can go
off and work in their out-of-tree codebase and not have to worry about
providing valid changelog entries and breaking their patches up into
logical pieces. They can take the time they have spend doing those
types of housekeeping chores and get the codebase into a much better
shape, and it can be submitted for inclusion into the real part of the
kernel tree when ready.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/lustre files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

In Lustre 2.4, the flags passed to the memory allocation functions are
translated from CFS enumeration values types to the kernel GFP
values by calling cfs_alloc_flags_to_gfp(). This function adds
__GFP_WAIT to all flags except CFS_ALLOC_ATOMIC. In 2.5, when
the cfs wrappers were dropped, cfs_alloc_flags_to_gfp() was
removed and the CFS_ALLOC_xxxx was simply replaced with __GFP_xxxx.
This means that most memory allocation calls are missing the
__GFP_WAIT flag. The result is that Lustre experiences more ENOMEM
errors, many of which the higher levels of Lustre do not handle
robustly.
Notes GFP_NOFS = __GFP_WAIT | __GFP_IO. So the patch replaces
__GFP_IO with GFP_NOFS.
Patch does not add __GFP_WAIT to GFP_IOFS. GFP_IOFS was not used in
Lustre 2.4 so it has never been used with __GFP_WAIT.

Lustre is the most deployed distributed file system
in the HPC (High Performance Computing) world. The patch
adds its client side support.
The code is not very clean and needs to live in drivers/staging
for some time for continuing cleanup work. See
drivers/staging/lustre/TODO for details.
The code is based on Lustre master commit faefbfc04
commit faefbfc0460bc00f2ee4c1c1c86aa1e39b9eea49
