V\u00fdvoj\u00e1r Jan Kara z firmy SUSE navrhol patch, ktor\u00fd odstra\u0148uje z jadra Linux k\u00f3d s podporou s\u00faborov\u00fdch syst\u00e9mov Xenix, SystemV\/386 a Coherent. Tento k\u00f3d je ozna\u010den\u00fd ako nepodporovan\u00fd (orphaned) od roku 2023 a odvtedy nebol nikto ochotn\u00fd ho udr\u017eiava\u0165. Spr\u00e1vca Christian Brauner, zodpovedn\u00fd za s\u00faborov\u00e9 syst\u00e9my v jadre, s\u00fahlasil s n\u00e1vrhom a prijal patch do vetvy vfs-6.15.

Pr\u00edbeh sa za\u010dal v roku 2002, ke\u010f bolo jadro Linux zbaven\u00e9 glob\u00e1lnej z\u00e1mky (BKL \u2013 Big Kernel Lock) v prospech granularnej\u0161\u00edch z\u00e1mok.
