[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I got guilted into this by this Twitter exchange:
https://twitter.com/axboe/status/1308778488011337728

Started with this patchset from June and revised it:
https://patchwork.kernel.org/project/dm-devel/list/?series=297693
(dropped MD patch while doing so_.

Tested these changes with this test Jens provided:

[mikes-test-job]
filename=/dev/dm-0
rw=randread
buffered=1
ioengine=io_uring
iodepth=16
norandommap

Jens, please feel free to pickup both patches, I don't have any
conflicting DM changes for 5.10.

Thanks,
Mike
