e8356fd233 blobstore: Cleanup after power failure while creating snapshot
Currently we are missing cleanup routine for case when
power failure interrupts creating snapshot. This patch
add such routine.

For the case where we find blob with a parent snapshot ID
matching newly created snapshot we can finish whole process
during recovery by processing forward with setting snpashot
as read only, removing xattr and syncing. We should remove
snapshot only if there is no blob with parent pointing at
snapshot.

Fixes github issue #760

f27cbce428 blobstore: Fix error path for snapshot creation
In _spdk_bs_snapshot_origblob_sync_cpl function on error
path we should not close snapshot as it will be closed during
volume closing when bs_dev is being destroyed.
This issue was found in unit test (see next patch in series).

622127d7e1 blobstore: Make possible to remove snapshot if there is only one clone
Starting with this patch it is possible to remove a
snapshot if there is only a one clone created from it.

In such case snapshot can be removed without any data
copying. This is achieved with following steps (case
with only one clone):
1. Open snapshot (Snapshot1) that shall be removed
2. Check if the Snapshot1 has no more than 1 clone (Clone1)
3. Remove Clone1 entry from Snapshot1
4. If the Snapshot1 has a parent snapshot (Snapshot2):
 4a. Add Clone1 entry to the Snapshot2 clones list
 4b. Remove Snapshot1 entry from Snapshot2 clones list
5. Open Clone1 blob
6. Freeze I/O operations on Clone1
7. Temporarily override md_ro flag for Snapshot1 and Clone1
   for MD modification
8. Merge Snapshot1 and Clone1 clusters maps into Clone1
   clusters map
9a. If Snapshot2 is present switch parent ID and backing
    bs_dev on Clone1
9b. If Snapshot2 is not present set parent ID to
    SPDK_BLOBID_INVALID and backing bs_dev to zeroes_dev
10. Sync MD on Clone1
11. Sync MD on Snapshot1
12. Restore MD flags for Clone1 and Snapshot1
13. Unfreeze I/O on Clone1
14. Close Clone1 blob
15. Remove Snapshot1

92cafd1586 blobstore: Remove blob on blobstore load when required
In some cases user may want to flag blob for removal
then do some operations (before removing it) and while

Example of such usage is delete snapshot functionality
that will be introduced in upcoming patch.

fde382d1ee blobstore: release same cluster as claimed during initial insert
When new writes come from different threads, cluster allocations can
happen many times at once. The corresponding cluster number for the map
is determined via _spdk_bs_allocate_cluster() and kept in ctx->new_cluster.

The cluster itself is inserted into the map only on md_thread.
When there is conflict of two threads allocating same cluster,
message is returned to the losting thread to release the cluster.

Before this patch, on such failure the cluster to release
was calcualted from the page. This resulted in releasing the
cluster claim for thread that actually won it.

This patch makes it so that cluster allocated and save in ctx
is used instead.

9e1116ea83 blob: pass correct op to spdk_bs_user_op_alloc in iov case
At some point this parameter may have been a bool, but it's
not now - so we need to explicitly pass SPDK_BLOB_READV or
SPDK_BLOB_WRITEV.

Otherwise we end up trying to write the iovec array as the
data buffer when executing this operation later - since we
passed "false" which is treated as 0 which is
SPDK_BLOB_WRITE (not SPDK_BLOB_WRITEV).

Fixes issue #603.

9e2eb8cb51 blobstore: Swap cluster maps on snapshot instead of copying
Previously, when creating a snapshot in blobstore the snapshot's cluster map
was copied from the "original" blob, with the original's map zeroed. These
operations are both O(num_clusters*cluster_size/page_size) while io
operations are frozen. This change replaces the linear operation with an
O(1) pointer swap at the critical moment that io is frozen, while
doing the zeroing before the freeze when preparing the snapshot to
minimize freeze time.

7c56c393ba bit_array: return UINT32_MAX if no cleared bits found
spdk_bit_array_find_first_set() returns UINT32_MAX if no
set bits are found.  But spdk_bit_array_find_first_clear()
would return the size of the bit array instead in this case.
(Note: the comments say size of the bit array + 1 which was
incorrect)

So this patch makes spdk_bit_array_find_first_clear()
consistent with spdk_bit_array_find_first_set() and returns
UINT32_MAX if no cleared bit is found.

eb8ee073c5 blobstore: recalculate total clusters after reading super block
Blobstore uses 1MB cluster size by default, but logical volumes
override it to 4MB by default.  When an existing lvolstore is loaded,
all cluster calculations were being done based on the 1MB size - not
the 4MB cluster size read from the superblock.  That would result
in asserts (due to mismatched used cluster mask size) and all kinds of
other possible weirdness with subsequent operations.

Fixes: 2c91e91907 ("blobstore: Save the original size of the disk.")
