* 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
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.
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 ...
+ 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
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.
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)
directly instead of relying on a symbol in rumpkern. I would like
to make it call the libc symbol directly, but I don't currently know
how to make it do that MI.
Makes hfs work (on i386), as it avoids endless recursion in bswap64().
Thanks to dillo for the image!
