f7cfd3a434 bdev/gpt: compare the correct MBR entry start LBA
The protective MBR entry may not be the first one.  This is already
handled correctly when comparing the total size field, but the start LBA
field was always looking at the first entry.

d695182200 bdev/gpt: fix MBR start_lba endian conversion

would print byte-swapped values on big-endian architectures.  On
little-endian architectures, the problem would not be noticeable, since
the conversion doesn't do anything.

bab34df6ca vhost: split iovs which span hugepage boundaries
A virtio descriptor may specify a buffer that spans
a huge page boundary or even a vhost memory region.
So modify spdk_vhost_vring_desc_to_iov() to take this
into account.

While here, also change spdk_vhost_vring_desc_to_iov
to return int instead of bool.  int return with -1 is
most standard to indicate failure.

542b541588 vhost_scsi: implemented abstract vhost event layer
Implemented abstract vhost event layer on top of virtio eventq.
This allows us to defer virtio-event-related actions to be called from
the vhost poller thread. This is required for hot-attach, for which
io_channels have to be created on the I/O thread.

This adds full support for hot-attaching and hot-detaching vhost scsi
devices. They can be now attached to a controller via RPC at any time.

40b74cd343 iscsi: optimization of large read process.
This patch move the spdk_iscsi_conn_handle_queued_tasks() to the main
loop of connection poller, make the logic more clear, it will also fix
one issue of hotplug:
for large read command, it has the potential risk:
one task will be split into N subtaks, when primary task return error and
try to send data in pdu, it will call spdk_iscsi_conn_handle_queued_tasks(),
the primary task is pending now, and all the subtasks will return error from
lun layer synchronous, this make the primary task return from the function
spdk_iscsi_transfer_in() after all the other subtaks, but when the N - 1 subtask
return from function spdk_iscsi_transfer_in(), it meet the condition:
primary->bytes_completed == primary->scsi.transfer_len
then it will send response pdu, after this, the primary task return from
spdk_iscsi_transfer_in(), it also meet the condition, so it will also try
to send response pdu, this will make the application run into error.

Consider the following scenario:
bdev X with 2 open descriptors A and B.
X is removed (hotremoved for instance)
bdev_unregister(X) is called
  * bdev->status = REMOVING
  * A->remove_cb is called
    * some poller is started
  * B->remove_cb is called
    * another poller started

* poller from A->remove_cb finishes it's work and closes the desc:
  * bdev_close(A)
    * A is removed from bdev->open_descs list
    * bdev->status is REMOVING, so bdev_unregister(X) is called again!
      * B->remove cb is called again!
        * another poller starts? segfault?

740e5dc50b iscsi: refactor and simplify digest calculations
Factor out the common PDU header and data digest calculations into
helper functions in iscsi.c.  This eliminates the need for the crc32c.c
iSCSI-specific padding functions spdk_fixup_crc32c() and spdk_crc32c(),
so remove them.

f71447e80d bdev: remove differentiation between bdev and vbdev modules
We still will sort the bdev_module list so that modules
with an examine() callback are initialized first.  This ensures

7fefd60fab bdev: make module init synchronous again
Module initializaiton was made asynchronous recently
to support bdev modules like gpt which need to do
asynchronous I/O.  But all modules now do any
asynchronous I/O in their examine() routines, and
init functions only do very basic operations to be
ready to handle examine() callbacks.

So simplify the bdev code and modules to go back to
a synchronous init procedure.

4fc7e66614 bdev: add vbdev claim/release semantics
vbdev modules still open/close bdevs as normal, but
should open bdevs read only when tasting (i.e. reading
the GPT to see if there are SPDK partitions).  When
a vbdev module is ready to claim the bdev for purposes
of creating virtual bdevs on top of it, it calls
spdk_vbdev_module_claim_bdev().  It can pass its
open descriptor as well to have it promoted to
write access (required for future vbdev modules like
logical volumes).

Note: error vbdev was changed to copy the base bdev
parameters one-by-one instead of a blind memcpy - we
do not want to copy the base bdev's vbdev_claim_module
into the new bdev!

e283c385e7 iscsi: fix AHS handling
Previously, we had a pdu->ahs pointer that was always NULL (never set
anywhere), and we would try to read data into this NULL pointer if the
initiator ever sent a PDU with a non-zero TotalAHSLength.

Rename the existing ahs_data array in the PDU to just "ahs" to minimize
the necessary changes.  We never actually dereference the ahs structure,
so its type is not important. (We can cast it later if we add support
for anything that requires an AHS.)

a6014eb2ad blobfs: process one set_xattr at a time
During RocksDB testing with MySQL, we found cases
where blobfs would try to update and sync the length
xattr on the underlying blob while an existing update
was already in progress.  This was primarily driven
by RocksDB performing appends and syncs on the log
file from multiple writer threads.

The simplest way to fix this is to just process one
sync_request at a time.  There could be a tiny bit
of inefficiency here if multiple threads are appending
and syncing a file in parallel - we can look at some
additional optimizations if we find a case where that
is noticeable.

cc7407947b jsonrpc: avoid calling poll() with a closed fd
If a connection is closed by the remote end, the JSON-RPC server could
potentially call poll() on the pollfd containing the invalid file
descriptor.  Rework the logic so that the pollfd's fd field is set to a
negative value so that poll() will ignore it until the connection is
fully cleaned up by spdk_jsonrpc_server_conn_remove().

Also add handling for the potential error conditions returned by poll()
so that if something does go wrong, the server doesn't get stuck polling
a broken pollfd forever.
