Raw Normal View History

Let pseudofs into the warmth of the FreeBSD CVS repo. It's not finished yet (I still have to find a way to implement process- dependent nodes without consuming too much memory, and the permission system needs tightening up), but it's becoming hard to work on without a repo (I've accidentally almost nuked it once already), and it works (except for the lack of process-dependent nodes, that is). I was supposed to commit this a week ago, but timed out waiting for jkh to reply to some questions I had. Pass him a spoonful of bad karma :)

Add support for process-dependent directories. This means that save for the lack of a man page, pseudofs is mostly complete now.

[the previous commit to pseudofs_vncache.c got the wrong log message] YA pseudofs megacommit, part 2: - Merge the pfs_vnode and pfs_vdata structures, and make the vnode cache a doubly-linked list. This eliminates the need to walk the list in pfs_vncache_free(). - Add an exit callout which revokes vnodes associated with the process that just exited. Since it needs to lock the cache when it does this, pfs_vncache_mutex needs MTX_RECURSE.
