Currently, the handling for errata #4 has two issues which allow
the checks for this issue to be bypassed using resumable sends.
The first issue is that drc->drc_fromsnapobj is not set in the
resuming code as it is in the non-resuming code. This causes
dsl_crypto_recv_key_check() to skip its checks for the
from_ivset_guid. The second issue is that resumable sends do not
clean up their on-disk state if they fail the checks in
dmu_recv_stream() that happen before any data is received.
As a result of these two bugs, a user can attempt a resumable send
of a dataset without a from_ivset_guid. This will fail the initial
dmu_recv_stream() checks, leaving a valid resume state. The send
can then be resumed, which skips those checks, allowing the receive
to be completed.
This commit fixes these issues by setting drc->drc_fromsnapobj in
the resuming receive path and by ensuring that resumablereceives
are properly cleaned up if they fail the initial dmu_recv_stream()
checks.

On kernels with KASAN enabled the following failure can be observed as
soon as the zfs module is loaded:
VERIFY(IS_P2ALIGNED(ptr, PAGE_SIZE)) failed
PANIC at spl-kmem-cache.c:228:kv_alloc()
The problem is kmalloc() has never guaranteed aligned allocations; this
requirement resulted in zfsonlinux/spl@8b45dda which removed all
kmalloc() usage in kv_alloc().
Until a GFP_ALIGNED flag (or equivalent functionality) is provided by
the kernel this commit partially reverts 66955885 and 6d948c35 to
prevent k(v)malloc() allocations in kv_alloc().

This commit adds the --saved (-S) to the 'zfs send' command.
This flag allows a user to send a partially received dataset,
which can be useful when migrating a backup server to new
hardware. This flag is compatible with resumable receives, so
even if the saved send is interrupted, it can be resumed.
The flag does not require any user / kernel ABI changes or any
new feature flags in the send stream format.

Currently, 'zfs list' and 'zfs get' commands can be slow when
working with snapshots that have a ds_props_obj. This is
because the code that discovers all of the properties for these
snapshots needs to read this object for each snapshot, which
almost always ends up causing an extra random synchronous read
for each snapshot. This performance penalty exists even if the
properties on that snapshot have been unset because the object
is normally only freed when the snapshot is freed, even though
it is only created when it is needed.
This patch allows the user to regain 'zfs list' performance on
these snapshots by destroying the ds_props_obj when it no longer
has any entries left. In practice on a production machine, this
optimization seems to make 'zfs list' about 55% faster.

where dentries for open files during a rollback are not invalidated.
The unrelated functionality for automatically unmounting .zfs/snapshots
was not reverted. Nor was the addition of shrink_dcache_sb() to the
zfs_resume_fs() function.
This issue was not immediately caught by the CI because the test case
intended to catch it was included in the list of ZTS tests which may
occasionally fail for unrelated reasons. Remove all of the rollback
tests from this list to help identify the frequency of any spurious
failures.
The rollback_003_pos.ksh test case exposes a real issue with the
long standing code which needs to be investigated. Regardless,
it has been enable with a small workaround in the test case itself.
