Subject: PR/45974 CVS commit: src/sys/miscfs/kernfs
Date: Tue, 4 Feb 2020 04:19:25 +0000
Module Name: src
Committed By: riastradh
Date: Tue Feb 4 04:19:24 UTC 2020
Modified Files:
src/sys/miscfs/kernfs: kernfs.h kernfs_vfsops.c kernfs_vnops.c
Log Message:
Use specfs vnops for specnodes in kernfs.
While here, don't filter out rootdev and rrootdev merely because
they're not cached.
Fixes the elusive /kern/rootdev and /kern/rrootdev nodes, which only
appeared sometimes when they felt like it, and fixes operations on
/kern/rootdev and /kern/rrootdev always returning EOPNOTSUPP.
We didn't seem to have a single PR for these issues but the following
PRs are all relevant:
