Hi all, I ran the latest blktests (git hash: acc408477e85) with v6.5-rc1 kernel and observed new failures those were not observed with v6.4. FYI, here I list the new failures. As for the failures observed with v6.4, please refer [1]. [1] https://lore.kernel.org/linux-block/lkmloyrqpebispffur5udxdiubmevvodtsvnap3jz7tv5ihstr@jg7ejye3bein/ List of new failures ==================== #1: block/004, block/005, zbd/005, zbd/006 #2: scsi/002 #3: zbd/010 Failure description =================== #1: block/004, block/005, zbd/005, zbd/006 The test cases fail when TEST_DEV is device-mapper, such as dm-linear. They fail because the test cases set /sys/block/*/queue/scheduler, which is no longer available for device-mapper from v6.5-rc1. Blktests fix will be required. I will work on the fix. #2: scsi/002 With kernel v6.5-rc1, /dev/sg* files are not created for SCSI devices. It makes scsi/002 fail. A kernel fix is posted [2].

A kernel fix candidate is posted [3]. [3] https://lkml.kernel.org/linux-f2fs-devel/20230711050101.GA19128@xxxxxx/
