OOM changes in Linux 3.7 lead to udev warnings and total breakage of KDE 3.5.10/TDE

2012-11-12 Thread Artem S. Tashkinov
Hello, If I remember correctly kernel developers promised not to break user APIs in the Linux kernel however in Linux 3.7 a /proc//oom_adj file has been totally removed which makes KDE 3.5.x (and I suppose TDE) unusable as they depend on this file and simply refuse to start in its absence.
