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.

lib/blob: Fix deleting a snapshot after decoupling it from its parent

When decoupling a snapshot from its parent, we need to clear its parent.
So we should remove the xattr BLOB_SNAPSHOT. Modifying the xattrs of a blob
only works if its metadata are not in read-only mode.
By default, a snapshot is in read-only mode so this operation fails. When we
later want to delete the snapshot, we will see that it has a parent, so we will
try to remove the snapshot from its parent's clones list. This will cause a
crash.
The fix is to remove the BLOB_SNAPSHOT xattr only after setting the snapshot's
metadata in rw mode.

check_format: For C files only, fix return type breaks

In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names

Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

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.

blobstore: Preallocate md_page for new cluster

When a new cluster is added to a thin provisioned blob,
md_page is allocated to update extents in base dev
This memory allocation reduces perfromance, it can
take 250usec - 1 msec on ARM platform.

Since we may have only 1 outstainding cluster
allocation per io_channel, we can preallcoate md_page
on each channel and remove dynamic memory allocation.

With this change blob_write_extent_page() expects
that md_page is given by the caller. Sicne this function
is also used during snapshot deletion, this patch also
updates this process. Now we allocate a single page
and reuse it for each extent in the snapshot.

lib/blob: do not assume realloc(NULL, 0) returns a not-NULL value

There is situation that num_extent_pages is zero and original pointer is
also NULL, the realloc() could return a Not NULL pointer.

Related UT has been added and updated.
1) In the default allocation (num_clusters == 0), the extent_pages is not allocated as expected.
2) In the thin provisioning allocation (num_clusters != 0), the extent_pages will be allocated if extent_table is used.

More related information as below:

The crux of the problem is that according to POSIX:

realloc: "If ptr is NULL, then the call is equivalent to malloc(size)"
malloc: "If size is 0, then malloc returns either NULL or a unique pointer value that can later be successfully passed to free"

blobstore was relying on realloc(NULL, 0) always return a unique pointer value, and not NULL. This is not portable behavior.

lib/blob: use bs_allocate_and_copy_cluster() in inflate

Using `bs_allocate_and_copy_cluster()` instead of a zero-length write
makes it possible to inflate/decouple snapshots, as the writes would
fail with -EPERM, because the snapshots are marked as read-only.

Additionally, zero-length non-vector requests are now completed
immediately. It makes it consistent with the vector path (which already
does that) and allows us to use the zero-length reads as a context for
cluster copy.

Fixes #2028.

lib/blob: force md update during decouple parent

Fixes #1933

When decoupling parent the updated parent_id was
not persisted to the blob if it was a snapshot.
Due to having md_ro set to true, blob_set_xattr()
failed.

Later on the incorrect parent_id could cause troubles
like in the github issue, when deleting that snapshot.

This patch adds return code check for blob_set_xattr
and forces md_ro to false during blob md sync.

Since some of code paths are shared between decouple,
inflate and clone operations, the final callback for them
is doing revert of the original md_ro.

Otherwise bs_io_unit_is_allocated() hits assert for thin

ut/blob: avoid modifying blob state in simultaneous sync test

This patch addresses couple issues:
1) Before issuing the md syncs the previous steps in test left
blob state in dirty state already. The resize never had a chance
to apply. This patch adds a proper md sync and polls for completion.

2) Changing blob state is something that should be done via API.
In order for dirty state to apply immidietly set_xattr is now used instead.

3) Verify test state in callbacks to make sure not only the number of
completions is correct, but their order.

This patch is introduced because of the test originally worked
only because of the extent pages always writing out its pages.
The second sync always was delayed because of this.
Meanwhile that should not be the case, since no MD or EP modification
was done.

Later in the series Extent Pages are fixed, but this test remained incorrect.

lib/blob: extent_page shall never occupy md page 0

Search for md_page to be used as extent page started
from 0, which is completely valid md_page.

This page can be free when for example blob with id 0
was deleted and some other requested a new page for extent.

There are already existing blobs that have extents
pointing to 0, which means unallocated.
Unfortunetly it means 0 can never mean md page 0.
If that already occured for someone, this extent page was already
lost during blob/bs reload and nothing can be done.

With this in mind following assumptions are made for extent pages:
- 0 means unallocated extent page
- UINT32_MAX means we ran out of md pages, and should not be persisted
- [NEW] extent page can never occupy md page 0

That last one is new addition in this patch.
bs_allocate_cluster will now always try to find md page from 1 or higher.

lib/blob: update pages array during blob load

When loading a blob and parsing its metadata,
the array of pages was not updated.
Serialization was unaffected, since the current pages
array is unused there.
Behavior was working correctly for first page,
but did not for any blob with more than one page.

Unfortunetly blob_persist_zero_pages() never zeroed out
the pages, neither blob_persist_zero_pages_cpl()
released the md pages.

Resulting in md pages being claimed even after blobs
deletion.

This patch now fills out the active pages array with
the appropriate page numbers from metadata.

blob: switch to bit_pool for tracking used_clusters

We still need to be able to explicitly set specific
bits in the cluster array during initialization and
loading (especially recovery), so we use a bit_array
during load, and then convert it to a bit_pool just
before calling the user's cmopletion callback.

This gives a roughly 300% improvement over baseline
on a benchmark which does continuous resize operations.
The benefit is primarily from saving the lowest free
bit rather than having to always start at bit 0. We
may be able to further improve this by saving extents
in the bit pool as well, although after this patch,
the benchmark shows other hot spots different from the
bit search.
