[DragonFlyBSD - Bug #3266] Filesystems broken due to "KKASSERT(count & TOK_COUNTMASK);"

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3266 has been updated by tkusumi.


Looks like this happens with kernel module filesystems.

I'm going to comment out this KASSERT since it works fine without it.
This assert may be correct, but then the real bug needs to be fixed.

Many fs including HAMMER2 are broken due to this assert failure.
Confirmed the panic with HAMMER2 and ext2.
It didn't happen a few months ago.
