Nyob rau hauv ib tug txij nkawm tso tawm lub kernel Qhov teeb meem yog nyob rau hauv DM (Device Mapper) subsystem, uas rau cov ntaub ntawv kev noj nyiaj txiag ntawm SSD drives. Qhov teeb meem pib tshwm tom qab , ntxiv rau cov ntsiav nyob rau lub Ib Hlis xyoo no, tsuas yog cuam tshuam rau 5.1 ceg thiab feem ntau ntawm cov xwm txheej tshwm sim ntawm cov tshuab nrog Samsung SSD drives uas siv cov ntaub ntawv encryption siv dm-crypt/LUKS dhau ntaus ntawv-mapper/LVM.
Ua rau qhov teeb meem Cov cim nruj dhau ntawm cov blocks pub dawb dhau ntawm FSTRIM (ntau qhov chaw tau cim rau ib lub sijhawm, tsis suav nrog max_io_len_target_boundary txwv). Ntawm cov kev faib khoom muab 5.1 ntsiav, qhov yuam kev twb raug kho nyob rau hauv , tab sis tseem tseem uncorrected nyob rau hauv (qhov kev kho no muaj, tab sis tam sim no nyob rau hauv "kev sim" ceg). Ib qho kev daws teeb meem rau kev thaiv qhov teeb meem yog kom lov tes taw fstrim.service/timer kev pab cuam, ib ntus rename fstrim executable cov ntaub ntawv, tshem tawm cov "tso tseg" chij los ntawm mount xaiv nyob rau hauv fstab, thiab lov tes taw "tso-discards" hom nyob rau hauv LUKS ntawm dmsetup .
