Ingo Molnar esitles teise versiooni pat\u0161ide kogumist, mis v\u00f5imaldab oluliselt v\u00e4hendada tuuma \u00fcmberkompileerimise aega, restruktureerides pealkirjafailide hierarhiat ja v\u00e4hendades ristansetundeid. Uus versioon erineb esimesest, mis ilmus paar p\u00e4eva tagasi, tuuma 5.16-rc8 kohandamise, t\u00e4iendavate optimeerimiste lisamise ja Clangi kompilaatori toetuse rakendamise poolest. Clangi kasutamisel v\u00f5imaldasid pat\u0161id v\u00e4hendada kompilatsiooniaega 88% v\u00f5i 77% CPU ressursi tarbimise n\u00e4itajate osas. T\u00e4ieliku tuuma \u00fcmberkompileerimise korral meeskonnaga «make -j96 vmlinux» v\u00e4henes kompilatsiooniaeg 337.788 sekundilt 179.773 sekundile. <\/p>\n

Uues versioonis on samuti lahendatud probleemid GCC pistikprogrammidega, parandatud algse \u00fclevaatamise k\u00e4igus avastatud vead ning toimunud on struktuuri «task_struct_per_task» deklareerimise dubleerimise \u00fchtlustamine. Lisaks on j\u00e4tkatud linux\/sched.h pealkirjafaili optimeerimist ja rakendatud RDMA (infiniband) alams\u00fcsteemi pealkirjafailide optimeerimist, mis on v\u00f5imaldanud veel 9% v\u00f5rra aegade v\u00e4hendamist v\u00f5rreldes esimese pat\u0161ide versiooniga. C-failide arv, mis \u00fchendavad linux\/sched.h pealkirjafaili, on v\u00e4henenud 68%-lt 36%-le v\u00f5rreldes esimese pat\u0161ide versiooniga (99%-lt 36%-le v\u00f5rreldes algse tuumaga).
