Hi Darrick, Unfortunately I'm having a bit of trouble with my USB keyboard and random key repeats, I lost several important messages this morning due to it. Your report of the xfstests generic/361 problem was one of them (as was Christoph's mail about the mount code location, I'll post on that a bit later). So I'm going to have to refer to the posts and hope that I can supply enough context to avoid confusion. Sorry about this. Anyway, you posted: "Dunno what's up with this particular patch, but I see regressions on generic/361 (and similar asserts on a few others). The patches leading up to this patch do not generate this error." I've reverted back to a point more or less before moving the mount and super block handling code around and tried to reproduce the problem on my test VM and I din't see the problem. Is there anything I need to do when running the test, other have SCRATCH_MNT and SCRATCH_DEV defined in the local config, and the mount point, and the device existing? This could have been a problem with the series I posted because I did have some difficulty resolving some conflicts along the way and may have made mistakes, hence reverting to earlier patches (but also keeping the recent small pre-patch changes).
