In la sii daayo dayactirka kernel-ka dhibaatadu waxay ku jirtaa nidaamka hoose ee DM (Device Mapper), kaas oo in xogta musuqmaasuqa ee drives SSD. Dhibaatadu waxay bilowday inay soo baxdo ka dib , oo lagu daray kernel bishii Janaayo ee sanadkan, kaliya waxay saamaysaa laanta 5.1 iyo inta badan kiisaska ayaa ka muuqda nidaamyada leh Samsung SSD Drives kuwaas oo isticmaala sirta xogta iyadoo la adeegsanayo dm-crypt / LUKS qalab-mapper / LVM.
Sababta dhibaatada Calaamadayn aad u daran oo ah baloogyada la sii daayay iyada oo loo marayo FSTRIM (waaxo aad u badan ayaa la calaamadeeyay markiiba, iyada oo aan xisaabta lagu darin xadka max_io_len_target_boundary). Qaybinta bixinta kernel-ka 5.1, khaladku mar hore ayaa lagu hagaajiyay , laakiin wali lama sixin gudaha (habaynta waa la heli karaa, laakiin hadda waxay ku jirtaa laanta "tijaabinta"). Hawsha ka hortagga dhibaatada waa in la joojiyo adeegga fstrim.service/timer, si ku meel gaar ah dib loogu magacaabo feylka fstrim la fulin karo, ka saar calanka "tuuro" ee ku yaala furaha fstab, oo dami qaabka "oggolaan-qaadista" ee LUKS iyada oo loo marayo dmsetup .
