eb91c4eee3 Use suspend with flush when device size was changed during table preload.
This allows online mirror resize, also removes condition to preventing
code to do this.

a9953411a8 o Rejig activation code device dependencies to make things a bit more robust
and further reduce the number of ioctl calls made.
o Metadata area struct change.
o Make config file accessible to activation functions & get stripe_filler
  from it.
o Allow kernel to return snapshot status as a fraction or a percentage.

8ef2b021ed Default stripesize 64k & config file setting for it;
Clear many compiler warnings (i386) & associated bugs - hopefully without
introducing too many new bugs:-)  (Same exercise required for other archs.)
Default compilation has optimisation - or else use ./configure --enable-debug

1951dba955 o Actually read snapshot percentage from the kernel - what a pain! :)
o Not sure if the code in dev_manager is really optimal, but it works..
   will look at adjusting it a bit now.
 o I *think* it works right when one snapshot if full but others aren't,
   but I haven't really been able to test it because the full snapshot
   somehow resets itself and weird things start happening to the system...

d8e7d77316 o dev_manager_suspend, untested. 2002-03-14 10:56:09 +00:00
Joe Thornber
0fe3a2c512 o Add comment describing what we're aiming for with dev_manager.
o  Remove dev_manager_reactivate, since it'll be the same as activate.

o  Merge the mark, visible and dirty fields into the same flags field.
