Just fixed many checkpath warnings/errors, added commit messages, fixed style issues and a real errors. This means the series is fairly clean at least in the context of checkpath

Closing this, as this was just a means to get the CI to build.

Darn it! I didn't read your latest commend before closing this. Sorry I am reopening this.

@igaw Ohh! Very smart to keep this PR open, that way we always trigger the build action with changes on the libnvme2 branch.

libnvme-mi was added after the initial 1.x release and it was decided to
ship it independ of libnvme. With the upcoming 2.x work, merge the two
libraries so it's possible to use common code, that is unify the APIs.

Signed-off-by: Daniel Wagner <wagi@kernel.org>
The root object will not only be used by the tree API, instead it will
be used as default context for the complete API. This addresses the
shortcoming that 'global' variables such as the logging infrastructure
should not be library global variables.

Signed-off-by: Daniel Wagner <wagi@kernel.org>
Abstract the file descriptor handle to a more abstract type so it's
possible to use different 'backends' to send/receive commands, e.g.
via MI instead direct.

The name 'link' was chosen because this name is not in use and thus we
avoid overloading existing names, such ctrl. The specification is using
'link' to describe the connection on a PCI bus which is kind of matching
how the handle is used in the library. It is the means to talk to a
controller.

There is no user left for the file descriptor in the args structs,
thus remove it.

Signed-off-by: Daniel Wagner <wagi@kernel.org>
When the user provides their own implementation of the passtrhu
function, it is necessary to use the file descriptor for the ioctl call.
Thus allow to retrieve the file descriptor from the link handle.

nvme-cli wants to retrieve the name of the device, add a getter for
this.

Signed-off-by: Daniel Wagner <wagi@kernel.org>
The nvme_link_t type is used for block device and char device. User
application sometimes need to figure out which type of device is used.
Because libnvme already knows the type of device expose this. This
avoids tracking of the device type in the user application.

generic transport abstraction type.

Hook up the MI backend to the generic commands API.

Signed-off-by: Daniel Wagner <wagi@kernel.org>
The MI code has an alignment and length check which the direct APIs are
missing. Without these checks the download tests for MI will fail after
using the generic APIs.

Renaming NVME_NVM_CDW* SHIFT and MASK enum members to
NVME_IOCS_COMMON_CDW*.
The ZNS IO command set (IOCS) has the same fields and offsets for the CDWs
in question.
Replacing STCR with two enum entries for CDW12 bit 25 as this bit can only
be Reserved, DEAC or PIREMAP. STCR is part of the copy command which has
its own enum members for CDW12.

The NVME_IOCS_COMMON_CDW* entries cover now
nvme_read
nvme_write
nvme_compare
nvme_write_zeros
nvme_write_uncorrectable
nvme_zns_append

This is in preparation for the following commit which introduces the
shift masks for the zone append command.
