Hi Jens,
Please consider pulling the following changes on top of tag
block-5.10-2020-12-05. This is to fix raid10 data corruption [1] in 5.10-rc7.
Tests run on this change:
1. md raid10: tested discard on raid10 device works properly (zero mismatch_cnt).
2. dm raid10: tested discard_granularity and discard_max_bytes was set properly.
Thanks,
Song
