[Bug 995163] Re: zcache should be built-in instead of kernel module
We're not going to fix this for Precise. Its a built-in staging driver with some serious issues.

[Bug 995163] Re: zcache should be built-in instead of kernel module
"stable" also includes fixes to "staging" drivers. I think there are two reasons why it is not included (yet): - no one submitted it to sta...@kernel.org yet - because it doesn't fix a bug (which is stable requirement) It is up to the distros to fix their kernel configs (which are not part of the upstream kernel). So I propose to either disable it (if risk is to high) or make it builtin. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995163 Title: zcache should be built-in instead of kernel module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/995163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@jsalisbury It's not in 3.2.18 and 3.3.6, and due to zcache is in staging currently, guess that it's not going to be included in linux-stable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995163 Title: zcache should be built-in instead of kernel module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/995163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 995163] Re: zcache should be built-in instead of kernel module
Sorry, I'm not subscribed to this mailing list so it's hard to reply... I use ZCACHE as a backend for cleancache on a low mem (512 MB) ARM machine (Tegra2/AC100) and I found it very useful (note: this machine not officially supported by Canonical, I just mentioned it as a usecase). Similar for ZRAM (also in staging and included in the Ubuntu kernel). On the other hand, I guess on x86 class machines it doesn't make much sense yet (except for visualization environments). But I still like it on my 2GB desktop because I often run huge compile jobs which benefit from more buffer cache. Also as pointed out by already, it is disabled by default and the remaining code seems to be safe to be included. So if you really feel uncomfortable with building it in, it may be disabled for x86 and enabled for ARMs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995163 Title: zcache should be built-in instead of kernel module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/995163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
