443b3c8f0b [io_engine (rust)] get_nr_blocks() wasn't handling block devices. 
Now calls file_utils::file_size()

ba7fd7bd2b [thin_check (rust)] Make --sync-io the default. 
For some systems you have to adjust the ulimits to get io_uring
to work, so we now default to using sync io.

Also added --async-io flag.

565c656ed2 [thin_generate_damage] Do not open a new transaction to prevent ref-count underflow 
There's a chance that thin_generate_damage tries to change ref-counts of
space map blocks due to its random nature, which could lead to problems.
If the ref-counts of metadata space map blocks (shadow source) is changed
to zero, then the ref-counts will become underflow after a shadow operation.

In-place space map modification is a way to prevent that value underflow.
An alternative approach is to avoid changing ref-counts of space map blocks.

1fe8a0dbde [thin_check] Allow using --clear-needs-check and --skip-mappings together 
Although it is not recommended to clear the flag without a full
examination, however, the usage has been documented as an approach
to reduce lvchange run time [1]. For the purpose of backward
compatibility and avoiding boot failure after upgrading thin_check [2],
the limitation is now removed.

b82307d8a5 [thin_check (rust)] drop O_DIRECT for the sync_io engine.

cda92de441 [thin_check (rust)] Add a threaded version of btree walk. 
Bottom level mappings use this if there are few devices.  Performance
is a bit slower for io_uring, and much slower for sync io (which I think
is due to io scheduling which I can't do much about).
