The collection attrs are often version specific. We should compare the
semantic PG metadata, if anything, not these!

We could conceivably mark the PG for backfill, but to do this correctly
we have to do the log rollback, which uses various methods in PG to update
snap metadata that we simply don't have access to from this tool.

Move all PG metadata (info, biginfo, epoch, and log) to a single per-PG
object. This should make it easier for ObjectStore implementations to
avoid lock contention in the write path.

This way we properly create the pgmeta object and set the infokey attr on
it. Break it into two steps, one part before split, one after.
Disable the collection_empty() check in split so that it doesn't trip over
this object.

There will be exactly one of these per PG. It slots into the flat
(pool, hash, name...)
namespace but is not a legal rados name (since it is the empty string).

From FileStore's perspective, nothing changed from v3 to v4. However, we
need to pass the do_upgrade flag to DBOjectMap open to trigger it's
upgrade process.

This ensures that we exercise the large xattr handling paths in the OSD.
(Specifically, we want to trigger DBObjectMap usage on EC objects so that
we can test the fix for #10171).

We were inadvertantly dropping the hash portion of the header key for EC
objects. This is usually not noticeable, but turns up quite quickly with
the new pgmeta objects, which share the same name ('') across PGs with
different hash values

A restriction that the w parameter of the cauchy technique is limited to
8, 16 or 32 was added incorrectly while refactoring parameter parsing in
the jerasure plugin and must be relaxed.

Signed-off-by: Loic Dachary <ldachary@redhat.com>
In the source code of cephfs there is no reference to it anymore,
but it's still in the man page. Leave it there for now, but make
it more clear that it is deprecated and unsupported.
It was possible for an image to be closed while aio operations
were still outstanding. Now all aio operations are tracked and
completed before the image is closed.
