below. The policy does not apply to non-Intel (C) notices.
git log --follow -C90% --format=%ad --date default <file> | tail -1
and then pull just the 4 digit year from the result.
Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.
Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line. Simply there for
consistency.

Adds ability to send trim commands to FTL - only 4MiB aligned requests (both
for offset and length of request) will be processed. During a trim
operation an L2P page (containing 1024 4B entries, 1 per user LBA; which
is where the 4MiB alignment comes from) will be marked as unmapped.
After this point any L2P access to that page will actually set the
entries themselves as FTL_ADDR_INVALID. This is done to make the trim as
fast as possible, since for large requests it's probable that most of
the L2P pages aren't actually in DRAM.

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.

This patch adds the ftl_batch strucutre, which describes a single batch
of data to be written to the disk. It's comprised of multiple write
buffer entries (the actual number depends on the write unit size of the
underyling device).
Additionally, a function responsible for filling out a batch was added.
It iterates over available IO channels and dequeues submitted write
buffer entries until a batch is completed. The IO channel queue is
shifted, so that each time the function is called a subsequent IO
channel is used first, which guarantees that all channels are treated
fairly.
