State Changed From-To: open->suspended This is a duplicate of kern/94269, and requires significant changes to nullfs in order to fix. Leave as suspended as it's effectively a feature request; more detailed information may be found in the above-referenced PR.
Responsible Changed From-To: freebsd-bugs->freebsd-fs Over to maintainer(s).
State Changed From-To: suspended->open Take it. I have prototyped VOP_VPTOCNP bypass for nullfs on CURRENT.
Responsible Changed From-To: freebsd-fs->kib Take.
Author: kib Date: Sun May 31 14:58:43 2009 New Revision: 193175 URL: http://svn.freebsd.org/changeset/base/193175 Log: Implement the bypass routine for VOP_VPTOCNP in nullfs. Among other things, this makes procfs <pid>/file working for executables started from nullfs mount.
