Looks like it. The test also is a bit overzealous as for copy on write file systems we can't do logical sector size aligned writes, e.g. btrfs or always_cow xfs. So we'll need to find a way to check for those cases.

Sorry, I saw this patch sitting by itself with no replies or "Hey I merged this" messages and thought we'd forgotten it. And if it's running without problems (I haven't seen any in generic/704) then I'll leave well enough alone. --D > > > > > Signed-off-by: Zorro Lang <zlang@kernel.org> > > > --- > > > > > > Hi, > > > > > > This reproducer was written for xfs, I try to make it to be a generic > > > test case for localfs.

Thanks for taking care this test :) There was a RVB for this patch: https://lore.kernel.org/fstests/20221107105309.khksga5m7p766sed@aalbersh.remote.csb/ This remind me that I still have some patches in my local branch, they were not merged by some reasons.

If the physical sector size is 4096, but the logical sector size is 512, the 512b dio write/read should be allowed. Signed-off-by: Zorro Lang <zlang@kernel.org> --- Hi, This reproducer was written for xfs, I try to make it to be a generic test case for localfs. Current it test passed on xfs, extN and btrfs, the bug can be reproduced on old rhel-6.6 [1]. If it's not right for someone fs, please feel free to tell me.
