84387d0fd3 Don't whine about wakeup() not being implemented every time it's 
called.  Nobody cares unless ltsleep() is called (and it panics).

b795ecbe79 fsync() device fd if doing a non-B_ASYNC write. This makes the 
file system safe, but less performant as the kernel, as it syncs
*all* outstanding dirty buffers.  However, we don't have much choice
in userspace currently.

1cf445da3e Don't play rename & typecast games with kauth_cred_t, but rather 
declare the type in rump.h only if necessary with the help of ifdef
magic.

system were run in the kernel.

4224c1d885 * in getpages, make sure we always align our buffer size to the page size 
* in putpages, make sure we don't try attempt to push data in a page
  after eof.  also, skip blocks which bmap can't locate (see comment
  in code).

the effect: file systems with fs_bsize < PAGE_SIZE now work r/w

3c2765f1a3 Hide NetBSD kernel headers completely from ukfs. This includes creating 
accessors for:
  * struct mount & VFS ops
  * struct uio
  * struct vnode
  * struct vattr

and some namespace games for:
  * namei flags
  * VOPs
  * enum vtype

Also, split rump services into two categories: library private and public
(rump_private.h and rump.h, respectively).

As a result, it is now possible to compile and use the NetBSD kernel
file systems on Linux (and probably other systems too with very
little work), although the makefiles need a bit of work to make it
a pleasureable experience.

34980d5637 Namespace management: do not call VOP_FOO directly from ukfs or 
p2k, but rather make the calls go through librump.  This avoids
having to include NetBSD kernel headers in userspace programs.
Stay tuned for some more mods of the same sort ...

cfd4dc8f38 Wrap malloc() so that we catch the kernel arguments (namely M_ZERO) 
properly.  It's fairly amusing that this wasn't noticed until now.

c360a79960 * split userspace file system access into two separate libraries: 
+ libp2k: the interface between libpuffs and vfs/vop
  + libukfs: generic user kernel file system library, usable
	     independent of libp2k and/or puffs
* use file system name (MOUNT_XYZ) instead of vfsops pointer to
  mount file system

643e56125f * move rump_vopwrite_fault() into history - we now support the file 
system faulting in pages if it does e.g. fragment reallocation
* get rid of rumpvm_findpage() and always use uvm_pagelookup()
* determine a vnode's cleanness by flagging it as being on the work
  list if we "take" a write fault and removing it from the worklist
  once pages are flushed.  There is no work list here, but at least
  there is symmetry with the kernel.

c3bc94628d Play catchup with ufs/ffs changes: compile subr_specificdata.c

36c0b176cc Fix it a bit & wait for the dust to settle. Also, enable UBC by default. 
ffs in userspace on top of puffs/p2k/rump is now stable enough to
host a make -j4 kernel build (well, at least my kernel build ...
but, yes, I am currently running that kernel on my desktop)
