Re: [Grml] Limit tmpfs RAM across mount points

* Mark 27e3kk302@sneakemail.com [20070117 23:15]:

What is the preferred grml way to limit total tmpfs RAM usage across all mount points. By default tmpfs takes 50% of RAM before swapout. We want a lower threshold of 20% RAM. With fstab syntax it's possible to limit one mount at a time, but is that the best one can do?

[...]

Yes.

Where is the 50% limit set, for example.

,---- [ $KERNELSOURCE/mm/shmem.c ] | if (!(sb->s_flags & MS_NOUSER)) { | blocks = totalram_pages / 2; `----
