Matthew Wilcox ettev\u00f5ttest Oracle, kes on tuntud nvme (NVM Express) draiveri ja DAX-failis\u00fcsteemi otsejuurdep\u00e4\u00e4su mehhanismi loomise poolest, on soovitanud eemaldada ReiserFS failis\u00fcsteemi Linuxi tuumast, sarnaselt vananenud failis\u00fcsteemide ext ja xiafs eemaldamisega, v\u00f5i l\u00fchendada ReiserFS koodi, j\u00e4ttes alles vaid kirjutamise ainult lugemise re\u017eiimi toe. <\/p>\n

Eemaldamise p\u00f5hjuseks on olnud t\u00e4iendavad raskused tuuma infrastruktuuri uuendamisel, kuna ReiserFS-i jaoks on arendajad pidanud tuumas hoidma vananenud AOP_FLAG_CONT_EXPAND lipu t\u00f6\u00f6tlust, kuna ReiserFS j\u00e4\u00e4b ainukeseks failis\u00fcsteemiks, mis kasutab seda lippu funktsioonis write_begin. Viimane parandamine ReiserFS koodis on kuup\u00e4evaga 2019 ja on ebaselge, kui n\u00f5utud see failis\u00fcsteem \u00fcldse on ning kas seda veel kasutatakse. <\/p>\n

Jan Kar\u00e1 ettev\u00f5ttest SUSE n\u00f5ustus, et ReiserFS on aegumas, kuid pole selge, kas see on piisavalt aegunud, et tuumast eemaldada. Jana s\u00f5nul j\u00e4tkab ReiserFS openSUSE ja SLES-is pakkumist, kuid sellel failis\u00fcsteemil on v\u00e4ike ja pidevalt kahanenud kasutajabaas. Ettev\u00f5tte kasutajatele l\u00f5petati ReiserFS-i tugi SUSE-s 3\u20134 aastat tagasi ning ReiserFS moodul ei kuulu vaikimisi tuuma paketisse. Alternatiivina soovitas Jan hakata andma hoiatusi ReiserFS-osade montaa\u017eimisel ja pidada seda failis\u00fcsteemi eemaldamiseks valmis, kui keegi ei avalda soovi selle kasutamist j\u00e4tkata aasta v\u00f5i kahe jooksul. <\/p>\n

Diskussioonile liitus Eduard Shishkin, kes toetab ReiserFS-i failis\u00fcsteemi, ja esitas pat\u0161i, mis eemaldab AOP_FLAG_CONT_EXPAND lipu kasutamise ReiserFS koodist. Matthew Wilcox aktsepteeris pat\u0161i oma harusse. Seega on eemaldamise p\u00f5hjus k\u00f5rvaldatud ja k\u00fcsimus ReiserFS-i sukeldamisest tuumas v\u00f5ib olla edasi l\u00fckatud piisavalt pikaks ajaks. <\/p>\n

K\u00fcsimust ReiserFS-i vananemise kohta ei saa t\u00e4ielikult k\u00f5rvale heita seet\u00f5ttu, et 2038. aasta probleemiga seonduv on endiselt lahendamata ning seet\u00f5ttu on ettevalmistatud ka XFS failis\u00fcsteemi neljanda versiooni tuumast eemaldamise ajakava (uus XFS formaat pakuti v\u00e4lja tuumas 5.10, ning ajastamise \u00fcletamine l\u00fckati edasi aastasse 2468). XFS v4 ehitus keelatakse vaikimisi 2025. aastal ja kood eemaldatakse 2030. aastaks. Sarnast ajakava tuleks v\u00e4lja t\u00f6\u00f6tada ka ReiserFS-i jaoks, andes v\u00e4hemalt viis aastat migreerimiseks teistele failis\u00fcsteemidele v\u00f5i muudetud metadatavormingutele.
