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.

Copy operation is defined by source and destination LBAs and LBA count
to copy. For destiantion LBA and LBA count we reuse exiting fields
`offset_blocks` and `num_blocks` in `struct spdk_bdev_io`. For source
LBA new field `src_offset_blocks` was added.
`spdk_bdev_get_max_copy()` function can be used to retrieve maximum
possible unsplit copy size. Zero values means unlimited. It is allowed
to submit larger copy size but it will be split into several bdev IOs.

When Link Time Optimization is enabled, compiler can sometimes produce
additional warnings saying that some variables may be uninitialized.
To supress the warning it is enough to add explicit initialization
of the variable causing the issue, in this case '*module_name = NULL'

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.
