Matthew Wilcox z firmy Oracle, znany z tworzenia sterownika nvme (NVM Express) oraz mechanizmu dost\u0119pu bezpo\u015bredniego do systemu plik\u00f3w DAX, zaproponowa\u0142 usuni\u0119cie systemu plik\u00f3w ReiserFS z j\u0105dra Linux, podobnie jak niegdy\u015b usuni\u0119to przestarza\u0142e systemy plik\u00f3w ext i xiafs, lub zredukowanie kodu ReiserFS, pozostawiaj\u0105c jedynie wsparcie dla trybu tylko do odczytu. <\/p>\n

Motywem do usuni\u0119cia by\u0142y dodatkowe trudno\u015bci z modernizacj\u0105 infrastruktury j\u0105dra, spowodowane tym, \u017ce specjalnie dla ReiserFS tw\u00f3rcy byli zmuszeni pozostawi\u0107 w j\u0105drze przestarza\u0142y procesor flagi AOP_FLAG_CONT_EXPAND, poniewa\u017c ReiserFS pozostaje jedynym systemem plik\u00f3w, kt\u00f3ry wykorzystuje t\u0119 flag\u0119 w funkcji write_begin. Ostatnia poprawka w kodzie ReiserFS pochodzi z 2019 roku i nie wiadomo, na ile ten system plik\u00f3w jest w og\u00f3le po\u017c\u0105dany i czy nadal jest u\u017cywany. <\/p>\n

Jan K\u00e1ra z firmy SUSE zgodzi\u0142 si\u0119, \u017ce ReiserFS zmierza ku przestarza\u0142o\u015bci, ale nie jest jasne, czy jest ju\u017c wystarczaj\u0105co przestarza\u0142a, aby usun\u0105\u0107 j\u0105 z j\u0105dra. Wed\u0142ug Jana, ReiserFS wci\u0105\u017c jest dostarczany w openSUSE i SLES, ale baza u\u017cytkownik\u00f3w tego systemu plik\u00f3w jest niewielka i stale si\u0119 zmniejsza. Dla u\u017cytkownik\u00f3w korporacyjnych wsparcie dla ReiserFS w SUSE zosta\u0142o zako\u0144czone 3-4 lata temu, a modu\u0142 z ReiserFS nie jest domy\u015blnie do\u0142\u0105czany do pakietu j\u0105dra. Jako alternatyw\u0119 Jan zaproponowa\u0142 rozpocz\u0119cie wy\u015bwietlania ostrze\u017cenia o przestarza\u0142o\u015bci podczas montowania partycji ReiserFS i uznanie tego systemu plik\u00f3w za gotowy do usuni\u0119cia, je\u015bli przez rok lub dwa nikt nie da zna\u0107 o ch\u0119ci dalszego korzystania z tego systemu. <\/p>\n

Do dyskusji do\u0142\u0105czy\u0142 Eduard Shishkin, kt\u00f3ry prowadzi system plik\u00f3w ReiserFS, i dostarczy\u0142 \u0142atk\u0119, usuwaj\u0105c\u0105 u\u017cycie flagi AOP_FLAG_CONT_EXPAND z kodu ReiserFS. Matthew Wilcox zaakceptowa\u0142 \u0142atk\u0119 w swojej ga\u0142\u0119zi. W ten spos\u00f3b pow\u00f3d do usuni\u0119cia znikn\u0105\u0142, a kwestia wy\u0142\u0105czenia ReiserFS z j\u0105dra mo\u017ce by\u0107 uznana za od\u0142o\u017con\u0105 na do\u015b\u0107 d\u0142ugi okres. <\/p>\n

Nie da si\u0119 ca\u0142kowicie zignorowa\u0107 problemu przestarza\u0142o\u015bci ReiserFS z powodu prac nad usuni\u0119ciem z j\u0105dra system\u00f3w plik\u00f3w z nierozwi\u0105zanym problemem roku 2038. Na przyk\u0142ad, z tego powodu ju\u017c opracowano harmonogram usuni\u0119cia czwartej wersji formatu systemu plik\u00f3w XFS (nowy format XFS zosta\u0142 zaproponowany w j\u0105drze 5.10 i przesun\u0105\u0142 przepe\u0142nienie licznika czasu do roku 2468). Kompilacja XFS v4 zostanie wy\u0142\u0105czona domy\u015blnie w 2025 roku, a kod usuni\u0119ty w 2030 roku. Podobny harmonogram ma zosta\u0107 opracowany tak\u017ce dla ReiserFS, udost\u0119pniaj\u0105c co najmniej pi\u0119\u0107 lat na migracj\u0119 do innych system\u00f3w plik\u00f3w lub zmienionego formatu metadanych.
