Hi! Thanks for your work. The patch seems to work for me on a vanilla 3.8.10, at least the hdds are no longer dropped from the raid. The code now ignores some request? What was the reason the disks fell off the raid? The discards are still passed to the ssd? Thanks, Markus Shaohua Li schrieb

Hi! Now I had the time to bisect, started with 3.7 as good and 3.8 as bad. 0cfbcafcae8b7364b5fa96c2b26ccde7a3a296a9 is the bad commit. [1] block: add plug for blkdev_issue_discard While 3.8.10 was still bad, the same kernel with the reverted patch applied is fine. I found another report. [2]
