A t\u00f6rl\u00e9s indoka a kernelinfrastrukt\u00fara fejleszt\u00e9s\u00e9nek tov\u00e1bbi neh\u00e9zs\u00e9gei voltak, mivel a ReiserFS miatt a fejleszt\u0151k k\u00e9nytelenek voltak megtartani az AOP_FLAG_CONT_EXPAND z\u00e1szl\u00f3 elavult kezel\u0151j\u00e9t, mivel a ReiserFS az egyed\u00fcli f\u00e1jlrendszer, amely ezt a z\u00e1szl\u00f3t haszn\u00e1lja a write_begin funkci\u00f3ban.

Jan K\u00e1ra a SUSE-t\u00f3l egyet\u00e9rtett, hogy a ReiserFS elavult \u00e1llapotba ker\u00fclt, de nem vil\u00e1gos, hogy ez el\u00e9g-e ahhoz, hogy elt\u00e1vol\u00edts\u00e1k a kernelb\u0151l. Jan szerint a ReiserFS tov\u00e1bbra is el\u00e9rhet\u0151 az openSUSE \u00e9s a SLES rendszerekben, de a f\u00e1jlrendszer felhaszn\u00e1l\u00f3inak sz\u00e1ma el negligible, \u00e9s folyamatosan cs\u00f6kken. \u00dczleti felhaszn\u00e1l\u00f3k sz\u00e1m\u00e1ra a ReiserFS t\u00e1mogat\u00e1sa a SUSE-n\u00e1l 3-4 \u00e9vvel ezel\u0151tt megsz\u0171nt, \u00e9s a ReiserFS modul alap\u00e9rtelmez\u00e9s szerint nincs benne a kernel csomagban.

A vit\u00e1hoz csatlakozott Eduard Shishkin, a ReiserFS f\u00e1jlrendszer karbantart\u00f3ja, \u00e9s beny\u00fajtott egy jav\u00edt\u00e1st, amely elt\u00e1vol\u00edtja az AOP_FLAG_CONT_EXPAND z\u00e1szl\u00f3 haszn\u00e1lat\u00e1t a ReiserFS k\u00f3dj\u00e1b\u00f3l.
