1831b086d0 blobfs: sync length if append occurs after cache eviction
Intermittent failures with the RocksDB tests pointed to
corruption in the MANIFEST file.  Further debug showed that
the MANIFEST file would be corrupted when its cache was
evicted.  Blobfs was partly handling append after cache
eviction - it would write the data to the correct position
within the blob.  But the sync path would not write the
updated file length xattr when the cache had been evicted.

463925ff0f blob: make spdk_blob_resize an async operation
To support resize operations during I/O, we will need
to send messages to each thread to quiesce I/O while
the resize operation is in progress to guard against
the cluster map memory changing while another thread
is accessing the cluster map.

Therefore, spdk_blob_resize needs to be asynchronous.

73358c99e1 util/nvme: added io_device unregister callback
Patch afe860ae deferred freeing the io_device. However, for nvme, the
io_device context (spdk_nvme_ctrlr) is still being destructed before
io_channels are destroyed, causing segfaults on hotremove.

This patch defers io_device context destruction and fixes nvme
hotremove.

Fixes: afe860aeb1 ("channel: Correctly defer unregisters if channels exist")
Fixes: 5533c3d208 ("util: defer put_io_channel")

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.

59ed2aa9f6 blobfs: lock accesses to sync fs_request list
Synchronous blobfs channels may allocate requests from
the synchronous thread, but free the request from the
async thread - especially for code that is shared between
sync and async modes.  So add a lock to the request list
for sync channels only.

Note this only affects metadata path (i.e. sync, delete, open)
and not I/O path.
