e9f0c576a3 Open stdin, stdout and stderr only after /etc/rc has executed. (/etc/rc 
executes it itself.) This avoids keeping /dev nodes on the temporary
root filesystem (initial mfs) in use unnecessarily.

68d0c4defe - code shared with exec() letting boot-time processes have 
their own fully fledged virtual address space and freeing
   their pre-allocated heap+stack area (necessary to let memory
   driver map in arbitrary areas of memory for /dev/mem without
   sys_vm_map)
 - small optimization preallocating memory on exec
 - finished VR_DIRECT physical mapping code

67d1b67805 exit prototype 2007-10-23 14:19:16 +00:00
Ben Gras
e8aec69c7b tweak to panic functions of mfs and vfs. 
. print newline
  . when recursive panic detected, don't simply return, confusing
    the caller, but print a diagnostic and exit
  . don't call sys_exit as this may confuse PM; it should be OK
    to call PM exit() nowadays.

38604e4e3a Don't truncate read requests based on v_size; v_size can be stale in the 
case of directories extended by subfilesystem. Rely on subfilesystem to
do read size truncating and return actual i/o size. This fixes bug 81 in
gforge, and unbreaks test 23.

4b1cd8c0ec Return EIO if a filedescriptor cannot be re-opened after a driver restart. 
Select now returns such a filedescriptor as ready (instead of EBADF). 
Reply before dev_up in FSSIGNON to avoid the problem that a DEV_OPEN
request is received by a driver that expects a reply from the FSSIGNON.
