staging: lustre: ldlm: disconnect speedup
disconnect takes too long time if there are many locks to cancel.
besides the amount of time spent on each lock cancel, there is a
resched() in cfs_hash_for_each_relax(), i.e. disconnect or eviction
may take unexpectedly long time. While this patch only contains
the client side fixes the original fix covered changes to both
the server and client code to ensure proper disconnect handling.
Below details the change done on both the server and client so
people can examine the disconnect behavior with both source bases.
- do not cancel locks on disconnect_export;
- export will be left in obd_unlinked_exports list pinned by live
locks;
- new re-connects will created other non-conflicting exports;
- new locks will cancel obsolete locks on conflicts;
- once all the locks on the disconnected export will be cancelled,
the export will be destroyed on the last ref put;
- do not cancel in small portions, cancel all together in just 1
dedicated thread - use server side blocking thread for that;
- cancel blocked locks first so that waiting locks could proceed;
- take care about blocked waiting locks, so that they would get
cancelled quickly too;
- do not remove lock from waiting list on AST error before moving
it to elt_expired_locks list, because it removes it from export
list too; otherwise this blocked lock will not be cancelled
immediately on failed export;
- cancel lock instead of just destroy for failed export, to make
full cleanup, i.e. remove it from export list.

staging: lustre: ko2iblnd: Adapt to the removal of ib_get_dma_mr()
In Linux kernel 4.9-rc1, the function ib_get_dma_mr()
was removed and a second parameter was added to ib_alloc_pd().
As this broke the building of the ko2iblnd module in
staging, the Kconfig for LNet has marked ko2iblnd as broken
and stopped building it.
This patch fixes this breakage by:
- Removing the BROKEN tag from lnet/Kconfig.
- Make it so the module parameter map_on_demand can no longer be
zero (we have to configure FMR/FastReg pools; it can no longer be
off).
- No longer try to use the global DMA memory region, but make use
of the FMR/FastReg pool for all RDMA Tx operations.
- Everywhere we are using the device DMA mr to derive the
L-key for non-registered memory regions, use the
pd->local_dma_lkey value instead.
- Make the default map_on_demand = 256. This will allow nodes with
this patch to still connected to older nodes without this patch
and FMR/FastReg turned off. When FMR/FastReg is turned off, we
use 256 as the max frags so the two sides will still be able to
communicate and work.
- Fix a mistake with BUILD_BUG_ON calls in o2iblnd.c which caused
compiling to fail.

The "jr3_pci" driver currently uses the `iobase` member of its private
device data `struct jr3_pci_dev_private` to store a pointer to its
ioremapped register region. Use the `mmio` member of the `struct
comedi_device` to store this instead, and remove the `iobase` member.
The `iobase` member was of type `struct jr3_t __iomem *`, with the
board's complicated register layout described by `struct jr3_t`. The
`mmio` member is a generic `void __iomem *`, so its value needs
converting to a `struct jr3_t __iomem *` for our purposes.
Change the clean-up in `jr3_pci_detach()` to call `comedi_pci_detach()`
instead of `comedi_pci_disable()`, as that will iounmap `dev->mmio` for
us.

staging: comedi: jr3_pci: re-work struct jr3_pci_subdev_private range
The `range` member of `struct jr3_pci_subdev_private` is an array of a
tag-less `struct` type whose layout is similar to `struct
comedi_lrange`. Both `struct` types end with a member also called
`range`. In the case of tag-less `struct` type, it is a single `struct
comedi_krange`. In the case of `struct comedi_lrange`, it is a flexible
array of `struct comedi_krange`.
Elements of the `range` array member in `struct jr3_pci_subdev_private`
are pointed to by elements of the `range_table_list` array member, which
are of type `const struct comedi_lrange *`. This requires some dodgy
type casting.
To avoid the dodgy type casting, change the element type of the `range`
member of `struct jr3_pci_subdev_private` to be a new type `union
jr3_pci_single_range`. This contains a member `l` of type `struct
comedi_lrange`, and an array member `_reserved` that is large enough to
encompass the `struct comedi_lrange` plus a single `struct
comedi_krange`. It is the same size as the previous type. Accesses to
`spriv->range[i].length` and `spriv->range[i].range` are replaced with
`spriv->range[i].l.length` and `spriv->range[i].l.range[0]` respectively
(where `spriv` is a `struct jr3_pci_subdev_private *`, and `i` is an
array index). Type-casted pointers to `spriv->range[i]` are replaced
with pointers to `spriv->range[i].l`, which do not require the type
casts. Since we defined a new type, we can define local variables of
the corresponding pointer type to shorten some lines of code. This is
made use of in `jr3_pci_alloc_spriv()`.

staging: comedi: jr3_pci: fix possible null pointer dereference
For some reason, the driver does not consider allocation of the
subdevice private data to be a fatal error when attaching the COMEDI
device. It tests the subdevice private data pointer for validity at
certain points, but omits some crucial tests. In particular,
`jr3_pci_auto_attach()` calls `jr3_pci_alloc_spriv()` to allocate and
initialize the subdevice private data, but the same function
subsequently dereferences the pointer to access the `next_time_min` and
`next_time_max` members without checking it first. The other missing
test is in the timer expiry routine `jr3_pci_poll_dev()`, but it will
crash before it gets that far.
Fix the bug by returning `-ENOMEM` from `jr3_pci_auto_attach()` as soon
as one of the calls to `jr3_pci_alloc_spriv()` returns `NULL`. The
COMEDI core will subsequently call `jr3_pci_detach()` to clean up.

the device is actually in reset. Given that this code doesn't bear
much resemblance to the original code, I'm changing the author of the
patch. This was tested on NS2 SVK.
Changes in v2:
* Reworked the first match to make it more obvious what portions of the
register were being preserved (Per Rafal Mileki)
* Style change to reorder the function variables in patch 2 (per Sergei
Shtylyov)
