9583e73901 lvol: remove lvs from global list after callback
Inserting into g_spdk_lvol_pairs list is done in vbdev_lvs_create_cb,
at that point it is known that it can be used. Meanwhile removing
was done at start of _vbdev_lvs_remove, to prevent possibility to
access it when waiting for destruct callback to complete.

This made checking if the g_spdk_lvol_pairs list is empty unreliable
to detect if all lvs were destroyed - they could still be being
processed and callback not yet called.

This patch removes lvs from global list only after the callback of
_vbdev_lvs_remove is called.

It will be used in future patch during asynchronous
finish of vbdev module to determine when all lvs were removed.

2196023bc7 lvol: consolidate vbdev_lvs_unload and vbdev_lvs_destruct
To avoid code duplication those two functions were merged.
New _vbdev_lvs_remove function deals with differences by
additional argument "destroy".

No functional difference should be observed after this patch.

ebf0312eef lvol: Add vbdev_lvs_destruct() and change unload behaviour [3/3]
This patch adds new API to remove logical volume store
from device it is on. It is only used from RPC, when
user explicitly requests. It allows to use the device to
use as any other bdev.

vbdev_lvs_unload() is now only called from hotremove and
during application shutdown. Which makes it possible to
load it again during application start up.

d189b8eedd blob_bdev: add unmap -> write_zeroes fallback
If the bdev doesn't support unmap, we should not send unmap I/O.
Instead, use spdk_bdev_write_zeroes(), which has a fallback in the bdev
layer for devices that don't natively support it.

e68e2e749b lvol: do not unload/destroy lvs when operation on lvol is pending
There is a scenario where we can try do unload or remove
lvol store while lvol present on that lvol store is being
closed or destroyed.

Scenario:
1. send delete_bdev rpc command
2. command returns before lvol is actually closed/destroyed
   (does not wait for callback)
3. send destroy_lvol_store rpc command
4. lvs is destroyed before lvol is destroyed
5. lvol destroy callback is called on destroeyd lvol store

Aboive scenario can be reproduced using:
spdk/test/vhost/spdk_vhost.sh --integrity-lvol-scsi

lvs_name/lvol_name name where these names are

In preparation for this change, rename the previous

to add a new lvol->name but keep the original
old_name during the transition.

08ac0074ce lvol: add unique lvolstore name
Each lvolstore now has a unique name which is persisted to
metadata.  Eventually this will provide a friendlier
way to reference logical volumes, in the form
lvolstore_name/lvol_name.

This patch only covers the unique lvolstore name.  An
lvolstore may not be created nor loaded if its name
conflicts with an already loaded blobstore.

Currently there is no way to rename an lvolstore to
resolve a conflict.  This will be coming in the future.

e36d36e4f9 bdev: fix write zeroes fallback error path
If an I/O fails during the write zeroes fallback to write on a split
I/O, the previous code would call spdk_bdev_io_complete() again on the
same I/O, causing infinite recursion.

Fix this by restoring the original user callback before completing the
I/O, as well as using _spdk_bdev_io_complete() rather than
spdk_bdev_io_complete() to avoid double-counting the statistics.

This also preserves the original bdev_io->status code set by the module,
rather than always setting it to SPDK_BDEV_IO_STATUS_FAILED.

3f9cbe513b blob: add write_zeroes support
Unmap does not guarantee that erased blocks will return all zeroes.
using write_zeroes when unmapping metadata gives the
desired behavior for a blob.

Only metadata pages will be cleared with write_zeroes in this patch;
blob data clusters will still call unmap.  This behavior may be made
configurable in a later patch (to allow the user to request zeroing of
clusters rather than just unmapping).

3fd7f28dc9 bdev: add fallback from write_zeroes to writev
if write_zeroes is not supported by the block device, we can get the
same behavior by simply writing a buffer full of zeroes to the blocks
we want to erase. I also incorporate splitting into the bdev layer to
accomodate large i/o.

5f5edbcb8c scsi_bdev: increase max I/O size to 4 MiB
This is necessary to avoid failing very large write_zeroes operations.

This is the minimal workaround to get the current bdevio tests to pass -
the real fix will be implemented in the bdev layer later.

There is no need to wait until an atexit() to unlink these - we can do it immediately
since the open refs will still be valid.

Note: changed the remove() calls to unlink() to be more precise, since these are

2df9f03c47 blobstore: New API call to destroy blobstore [1/3]
Currently exposed API allows to load/unload and to
initialize blobstore on a device.

A spdk_bs_destroy() call is added in order to reach
functional parity with spdk_bs_init(). It was not
possible to remove blobstore from device from within
SPDK previously.

spdk_bs_destroy() takes blobstore pointer as argument
(instead of bs_dev), because blobstore has to be already
loaded to destroy it.

if the system crushed, we have no chance to sync the used md bitmap and
used clusters bitmap into disk, then next time when we try to load the
blobstore, all the data will lost, this patch add the logic to recover the
valid data from last dirty shutdown. We will go through all the metadata pages

f97c8b3142 lvol: add spdk_lvs_opts_init()
Some future patches will require specifying an lvol_store
name when calling spdk_lvs_init().  This means that passing
NULL for spdk_lvs_opts will no longer be an option.  So
add an spdk_lvs_opts_init() (similar to spdk_bs_opts_init)
which will initialize a default value for the cluster size.

While here, prepend an underscore to spdk_setup_lvs_opts, since
this function is not part of the public SPDK API.
