443b3c8f0b [io_engine (rust)] get_nr_blocks() wasn't handling block devices.

 2020-12-02 15:20:14 +00:00
Joe Thornber
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.

f4c3098e02 [thin_check (rust)] fix bug in key range splitting. 
Ranges were not being ommitted when a block was ommitted due to
being shared and already visited.

b82307d8a5 [thin_check (rust)] drop O_DIRECT for the sync_io engine. 
O_DIRECT slows us down, and there's no correctness reason for having it.
 2020-08-21 11:39:41 +01:00
Joe Thornber
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).
