Replace most BSD 3-clause license text with SPDX identifier. Many open source projects have moved to using SPDX identifiers to specify license information, reducing the amount of boilerplate code in every source file. This patch replaces the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause identifier. Almost all of these files share the exact same license text, and this patch only modifies the files that contain the most common license text. There can be slight variations because the third clause contains company names - most say "Intel Corporation", but there are instances for Nvidia, Samsung, Eideticom and even "the copyright holder". Used a bash script to automate replacement of the license text with SPDX identifier which is checked into scripts/spdx.sh.

ftl: Initial implementation This patch adds core FTL (flash translation layer) submodules. On regular SSDs the FTL is part of firmware, whereas Open Channel enables moving it to the host and allows for having full controll of data placement on the device.

so_ver: increase all major versions To allow SO_MINOR updates on LTS for the whole year it is supported, the major version for all components needs to be increased. This is to prevent scenario where two versions exists with matching versions, but conflicting ABI. Ex. Next SPDK release adds an API call increasing the minor version, then LTS needs just a subset of those additions. Increasing major so version after LTS, allows the future releases to update versions as needed. Yet allowing LTS to increase minor version separately. Disabled test for increasing SO version without ABI change, as that is goal of this patch. This check shall be removed with SPDK 22.05 release. This patch: - increases SO_VER by 1 for all components - resets SO_MINOR to 0 for all components - removes suppressions for ABI tests Signed-off-by: Tomasz Zawadzki <tomasz.zawadzki@intel.com> Change-Id: Id1a5358882dc496faa5b0b5c9a63b326c378c551 Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/11361 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Community-CI: Broadcom CI <spdk-ci.pdl@broadcom.com> Reviewed-by: Jim Harris <james.r.harris@intel.com> Reviewed-by: Ben Walker <benjamin.walker@intel.com>

This means that the "rwb" module and all of its references were removed and replaced with the recently added interfaces.

ftl: Gathering asynchronous NAND management events The patch adds support for retrieving asynchronous media management events sent by the drives. SSDs needs to inform the host of various incidents concerning the data placed on the media. The events include wear-leveling, read disturb, and background data refresh. In order to poll for this asynchronous events, a separate thread is added that polls for completion of admin commands for each of Open Channel disk and dispatches the ANM events to the appropriate block devices.
