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.

e2f06e7c89 Directory check before access check. 2007-08-08 15:26:47 +00:00
Philip Homburg
a116b3aa55 To return the right error, check first is an object is a directory (for 
mkdir, rmdir/unlink, mknod), simply pipe code by using v_pipe_rd_pos and
v_pipe_wr_pos directly. Some cleanup work in open.c
