[DragonFlyBSD - Bug #3179] KKASSERT(bp->b_flags & B_VMIO);

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #3179 has been updated by dillon.


The buffer cache used to have B_MALLOC buffers, but I recently removed those so it should now generally only be able to have B_VMIO buffers.  There are specialized buffers that are not B_VMIO, but they are not attached to vnodes and do not use the brelse() mechanism.

I'm not sure if I want to remove that else clause yet (line 1520-1531), but it does warrant clarification in the code comment so I will adjust the comment for now.

This call

looks to be incorrect given
https://github.com/DragonFlyBSD/DragonFlyBSD/blob/master/sys/kern/vfs_bio.c#L3050

Not really sure how this "else" case happen though, as filesystem buffers are all B_VMIO (if not IO_VMIO).
