pooka 18e91c156a Don't fool around when recycling vnodes, simply override refcount to 1, hold on tight to your hat, and call recycle. The reason is that we might pick up extra references such as from lookup and we don't really care about tracking those. For example with p2k, puffs in the kernel already does all the refcounting we could ever dream of, and therefore it's left to the client and unnecessary.		2008-01-27 20:01:29 +00:00

    Runnable Userspace Meta Programs

Quick rundown of the current directory structure:

/librump - kernel runtime emulation
  /rumpkern - portion compiled with -D_KERNEL, uses kernel headers
  /rumpuser - userspace namespace support for previous, *NO* -D_KERNEL
	      provides e.g. malloc() and some syscalls

/include
  /machine - headers meant to be used for rump compilation when the MD
	     ones cause too much trouble, e.g. curlwp which is different
	     from arch to arch

/fs - file system rumps
  /lib - libraries used by fs rumps
    /lib$fs  - kernel file system code compiled out of /sys with -D_KERNEL
    /libp2k  - puffs-to-vfs adaption layer, userspace namespace
    /libukfs - user kernel file system, a library to access file system
	       images (or devices) directly in userspace without going
	       through a system call and puffs
  /bin - rumps themselves.  fsconsole uses ukfs directly.  the rest are
	 file system specific rumps and use puffs
