Ben Gras aac4f32f51 Don't print SIGKSTOP message 2005-10-21 11:28:50 +00:00
Ben Gras 1a37474437 . minor formatting fixes (spaces, newlines) of messages 
. check pids for being > 0 before kill()ing them (0 and negative
  numbers have special meanings that shouldn't be used)

Ben Gras 629453fba8 Added explanation of SIGKILL, REBOOT order. 2005-10-21 11:10:16 +00:00
Ben Gras 5333d4f4e4 . don't kill tty, send it messages on signals 
. kill processes first, then tell fs to reboot (otherwise fs will have
  exited its processes and be confused when they exit again)

Ben Gras f6bdd6a4a9 New DMAP_BABY flag in <minix/dmap.h> and to be printed by IS in dmap dump. 2005-10-20 19:40:44 +00:00
Ben Gras b5e3e6d18c Two 'dynamic driver' features in FS: 
.  When drivers disappear that have pending select()s, wake up
   those user processes with EAGAIN so that they can retry their
   select() and won't hang forever on it.
.  When drivers re-appear and are mapped into the dmap, run through
   the list of mounted filesystems and re-dev_open() every one (for
   partition tables and such). This can't happen before the driver
   has exec()ced itself, so processes that have fork()ed but not
   exec()ced yet are marked as DMAP_BABY in the dmap table if they
   are dmapped before they are execced. If that happens, the above
   procedure happens after the exec(). If the exec() happens before
   the dmapping, it (the dev_open()ing) happens right away.

Ben Gras 4dfe841667 No driver in dmap is NONE instead of 0. 2005-10-10 14:27:41 +00:00
Ben Gras 86ed54ee94 FS: 
. unmap device drivers from dmap when PM signals they are dead
	. new null-io function (no_dev_io) to fill in for io functions
	  of unmapped drivers
	. driver (process number) of unmapped drivers is NONE instead of
	  0 (a valid process number)

IS:
	. print mutable flag of dmap table too

FS changes require sync() to be done 'manually' (currently by
reboot/shutdown) at shutdown time; could be caught by SIGTERM in
the future.
