SturmFlutDoes anybody here know about the kernels we run on Ubuntu phones? I am trying to figure out the content of /proc/timer_stats and there is an oddity which doesn't seem to show up on my desktop11:17

melodieI need to ask an information to the ubuntu kernel packagers and devs : in Vivid the zram module is loaded by default, even though it's configured as module and not hard in the configuration of the kernel. And there is a module having for name ZRAM_LZA_COMPRESS default loaded (y). It seems that the zram-lza-compress module would call zram to be default loaded if zram isn't blacklisted. My question is this: is my statement true? Am I right to 16:21
melodiethink the zram-lza-compress is what triggers zram to be loaded at boot time?16:21
melodiethis is my actual kernel:16:21
melodie3.19.0-22-generic #22-Ubuntu SMP Tue Jun 16 17:15:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux16:21
melodieand I have noticed this behavior in all former kernels since I moved to Vivid.16:22
melodieso what is it that really happens here,16:22
melodie?16:22
melodieit's about bug #1449678 except that something was changed in the original description : "non english locales" was added by some folk, no idea why, I think it's unrelated16:31

melodiewhile I'm here, the fix doesn't work16:32
melodiecan't work is my guess16:32
melodieexcept if zram is prior blacklisted in the /etc/modules.d/blacklist.conf ;-)16:34
melodieI think I am right, the kernel is faulty.16:48
