The only place vn_rename and vn_remove are used is when writing
out an updated pool configuration file. By truncating the file
instead of renaming and removing it we can avoid having to implement
these interfaces entirely. Functionally an empty cache file is
treated the same as a missing cache file. This is particularly
advantageous because the Linux kernel has never provided a way
to reliably implement vn_rename and vn_remove.
The cachefile_004_pos.ksh test case was updated to understand
that an empty cache file is the same as a missing one.
The zfs-import-* systemd service files were not updated to use
ConditionFileNotEmpty in place of ConditionPathExists. This
means that after exporting all pools and rebooting new pools
will not the scanned for on the next boot. This small change
should not impact normal usage since pools are not exported
as part of a normal shutdown.
Documentation was updated accordingly.

This patch resolves an issue where raw sends would fail to send
encryption parameters if the wrapping key was unloaded and reloaded
before the data was sent and the dataset wass not an encryption root.
The code attempted to lookup the values from the wrapping key which
was not being initialized upon reload. This change forces the code to
lookup the correct value from the encryption root's DSL Crypto Key.
Unfortunately, this issue led to the on-disk DSL Crypto Key for some
non-encryption root datasets being left with zeroed out encryption
parameters. However, this should not present a problem since these
values are never looked at and are overrwritten upon changing keys.
This patch also fixes an issue where raw, resumable sends were not
being cleaned up appropriately if an invalid DSL Crypto Key was
received.

Several issues were uncovered by running stress tests with zfs
encryption and raw sends in particular. The issues and their
associated fixes are as follows:
* arc_read_done() has the ability to chain several requests for
the same block of data via the arc_callback_t struct. In these
cases, the ARC would only use the first request's dsobj from
the bookmark to decrypt the data. This is problematic because
the first request might be a prefetch zio which is able to
handle the key not being loaded, while the second might use a
different key that it is sure will work. The fix here is to
pass the dsobj with each individual arc_callback_t so that each
request can attempt to decrypt the data separately.
* DRR_FREE and DRR_FREEOBJECT records in a send file were not
having their transactions properly tagged as raw during raw
sends, which caused a panic when the dbuf code attempted to
decrypt these blocks.
* traverse_prefetch_metadata() did not properly set
ZIO_FLAG_SPECULATIVE when issuing prefetch IOs.
* Added a few asserts and code cleanups to ensure these issues
are more detectable in the future.

Because resuming from a token requires "guid" -> "snapshot" mapping
we have to walk the whole dataset hierarchy to find the right snapshot
to send; when both source and destination exists, for an incremental
resumable stream, libzfs gets confused and picks up the wrong snapshot
to send from: this results in attempting to send
"destination@snap1 -> source@snap2"
instead of
"source@snap1 -> source@snap2"
which fails with a "Invalid cross-device link" error (EXDEV).
Fix this by adjusting the logic behind dataset traversal in
zfs_iter_children() to pick the right snapshot to send from.
Additionally update dry-run 'zfs send -t' to print its output to
stderr: this is consistent with other dry-run commands.

With the addition of the ABD changes consumption of the virtual
address space has been greatly reduced. This exposed an issue on
CONFIG_HIGHMEM systems where free memory was being calculated
incorrectly. Functionally this didn't cause any major problems
prior to ABD because a lack of available virtual address space
was used as an indicator of low memory.
This patch makes the following changes to address the issue and
in the process realigns the code further with OpenZFS. There
are no substantive changes in behavior for 64-bit systems.
* Added CONFIG_HIGHMEM case to the arc_all_memory() and
arc_free_memory() functions to only consider low memory pages
on CONFIG_HIGHMEM systems.
* The arc_free_memory() function was updated to return bytes
instead of pages to be consistent with the other helper
functions. In user space we make up some reasonable values
since currently only testing is performed in this context.
* Adds three new values to the arcstats kstat to provide visibility
in to the ARC's assessment of the memory situation:
memory_all_bytes, memory_free_bytes, and memory_available_bytes.
* Added kmem_reap() call to arc_available_memory() for 32-bit
builds to realign code with OpenZFS.
* Reduced size of test file in /async_destroy_001_pos.ksh to
speed up test case. Multiple txgs are still required.
* Move vdevs used by zpool_clear_001_pos and zpool_upgrade_002_pos
to TEST_BASE_DIR location to speed up test cases.

When receiving a FREEOBJECTS record, receive_freeobjects()
incorrectly skips a freed object in some cases. Specifically, this
happens when the first object in the range to be freed doesn't exist,
but the second object does. This leaves an object allocated on disk
on the receiving side which is unallocated on the sending side, which
may cause receiving subsequent incremental streams to fail.
The bug was caused by an incorrect increment of the object index
variable when current object being freed doesn't exist. The
increment is incorrect because incrementing the object index is
handled by a call to dmu_object_next() in the increment portion of
the for loop statement.

Commit d3c2ae1 introduced a dbuf cache with a default size of the
minimum of 100M or 1/32 maximum ARC size. (These figures may be adjusted
using dbuf_cache_max_bytes and dbuf_cache_max_shift.) The dbuf cache
is counted as metadata for the purposes of ARC size calculations.
On a 1GB box the ARC maximum size defaults to c_max 493M which gives a
dbuf cache default minimum size of 15.4M, and the ARC metadata defaults
to minimum 16M. I.e. the dbuf cache is an significant proportion of the
minimum metadata size. With other overheads involved this actually means
the ARC metadata doesn't get down to the minimum.
This patch dynamically scales the dbuf cache to the target ARC size
instead of statically scaling it to the maximum ARC size. (The scale is
still set by dbuf_cache_max_shift and the maximum size is still fixed by
dbuf_cache_max_bytes.) Using the target ARC size rather than the current
ARC size is done to help the ARC reach the target rather than simply
focusing on the current size.
