mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

fvdl ebffddb531 Bump last argument to VOP_READDIR to off_t (from u_long). 1997-10-10 02:01:02 +00:00
leo e0f973ee3b Implement the kernel part of pr-1891. This allows for a more flexible sized
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

mycroft e3f99a9397 Pass the vnode type to vaccess(), and use it when checking VEXEC. Make sure
that the mode bits passed to vaccess() and returned by foo_getattr() contain
only permission bits.

cgd 90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...
1996-12-22 10:10:12 +00:00
cgd a67c0b16b8 define path name string variables that we should not (and, thankfully, do
not) modify as 'const char *' rather 'char *'.

mycroft 53fccab940 Fix vop_link, vop_symlink, and vop_remove semantics in several ways:
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
