But that was exactly the problem. I ran out of physical and swap
memory, so root couldn't get a login to fix things. I can add yet
another 128Mb swapfile and be happy about that UNTIL this swapfile is
exhausted too. Then I will be in deep sh*t again ......
To clear things up:
1) If you reserve memory using 'rootpages' you reserve a part of the
TOTAL memory available. NOT only from the PHYSICAL memory
available. So, if you have 512Mb physical mem and 512Mb swap mem, you
reserve some pages from 1Gig available memory - the pages might be
swapped out, they might be swapped in ... But only root can use them,
making root able to clean up things if the memory pool available to
ordinary users seems exhausted.
2) The amount written to 'rootpages' is currently the number of pages
to reserve. Let's keep it that way - the conversion from Mb/Kb is
better left to a non-kernel program (can easily be done in a
shell-script ;o)
3) I sense that people doesn't quite 'like' the patch (idea). That's
fine with me. All I asked for was for somebody to spend 5 minutes on
validating the changes so that I could safely use the patch for private
purpose ....
Kind regards,
Brian
