https://bugzilla.kernel.org/show_bug.cgi?id=186551 --- Comment #7 from Eric Sandeen <sandeen@xxxxxxxxxxx> --- Those seem to be spaced out at roughly 4G boundaries - 4k short of 4G if my math is right. Not sure what that implies though. You might try with "-v" and/or trying smaller step values with blkdiscard to see if anything works. What do /sys/block/nvme0n1/discard_alignment and /sys/block/nvme0n1/queue/discard_granularity contain? -- You are receiving this mail because: You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
