https://bugzilla.kernel.org/show_bug.cgi?id=202349 --- Comment #9 from nfxjfg@xxxxxxxxxxxxxx --- On the kernel which I ran the tests: # zcat /proc/config.gz |grep WBT CONFIG_BLK_WBT=y # CONFIG_BLK_WBT_SQ is not set CONFIG_BLK_WBT_MQ=y I can't reproduce any of this when running the same test script on an ext4 formatted disk under the same circumstances (different disk, but comparable speed). -- You are receiving this mail because: You are watching the assignee of the bug.
