The implementation for Open-Channel SSDs is divided into media
management and targets. This patch implements a generic media manager
for open-channel SSDs. After a media manager has been initialized,
single or multiple targets can be instantiated with the media managed as
the backend.

This target allows an Open-Channel SSD to be exposed asas a block

It implements a round-robin approach for sector allocation,

The first generation of Open-Channel SSDs is based on NVMe. The NVMe
driver is extended with support for the LightNVM command set.
Detection is made through PCI IDs. Current supported devices are the
qemu nvme simulator and CNEX Labs Westlake SSD. The qemu nvme enables
support through vendor
This patchset implements support for Open-Channel SSDs.
Applies against Jens' for-4.4/drivers and is available through the lkml_v12
branch at:
https://github.com/OpenChannelSSD/linux
Changes since v11:
- Add support for group identifiers.
- Fixed kbuild error on nvme_nvm_unregister.

Hi All,
As discussed in the recent "On-demand device probing" thread and in a Kernel
Summit session earlier today, there is a problem with handling cases where
functional dependencies between devices are involved.
What I mean by a "functional dependency" is when the driver of device B needs

If a suitable prepare callback cannot be found for a given device and
its driver has no PM callbacks at all, assume that it can go direct to
complete when the system goes to sleep.
The reason for this is that there's lots of devices in a system that do
no PM at all and there's no reason for them

string_get_size() can't really handle huge block sizes, especially
blk_size > U32_MAX but string_get_size() interface states the opposite.
Change blk_size from u64 to u32 to reflect the reality.

string_get_size() loses precision when there is a remainder for
blk_size / divisor[units] and size is big enough. E.g
string_get_size(8192, 4096, STRING_UNITS_10, ...) returns "32.7 MB"
while it is supposed to return "33.5 MB". For some artificial inputs
the result can be ridiculously wrong, e.g.
Add a couple of simple tests for string_get_size().

Changes since v1:
- Make test_string_get_size_one() check both STRING_UNITS_2 and
STRING_UNITS_10 in one shot [Rasmus Villemoes]
- Check U64_MAX instead of some-very-big-number.

Linux always lies about your storage size when it has 4k sectors and its
size is big enough. E.g. a device with 8192 4k sectors will be reported as
"32.7 MB/32 MiB" while "33.5 MB/32 MiB" is expected. This series is
supposed to fix the issue by fixing calculation precision in
string_get_size() for

If that is happening, that sounds like a hardware and/or firmware bug.

Mask the cycle values before subtraction. So we can use this
validation while the clocksource mask is not 64-bits.

In multi-core system, if the clock is not sync perfectly, it
will make cycle_last that recorded by CPU-A is a little more
than cycle_now that read by CPU-B. With the negative result,
hrtimer_update_base() return a huge and wrong time. It leads
to the cpu can not finish the while loop in
