Ingo Molnar esitles teise versiooni patareipakettidest, mis v\u00f5imaldavad m\u00e4rkimisv\u00e4\u00e4rselt v\u00e4hendada tuuma uuesti kompileerimise aega, restruktureerides pealkirjade hierarhiat ja v\u00e4hendades rists\u00f5ltuvuste arvu. Uus versioon erineb esimesest variandist, mis esitati paar p\u00e4eva tagasi, kohandamise ja tuuma 5.16-rc8 toetamise ning t\u00e4iendavate optimeerimiste lisamise poolest. Clangi kasutamisel on pat\u0161ide rakendamine v\u00f5imaldanud v\u00e4hendada kompileerimise aega 88% v\u00f5i 77% CPU ressursikasutuses. T\u00e4ieliku tuuma uuesti kompileerimise korral k\u00e4suga «make -j96 vmlinux» v\u00e4henes kompileerimise aeg 337.788 sekundilt 179.773 sekundile. <\/p>\n

Uues versioonis on lahendatud GCC pluginate probleem, parandatud algse \u00fclevaatuse k\u00e4igus tuvastatud vead ning viidud l\u00e4bi \"task_struct_per_task\" struktuuri deklareerimise dubleeringute \u00fchtekuuluvus. Samuti on j\u00e4tkatud linux\/sched.h pealkirjafaili optimeerimist ja ellu viidud RDMA (infiniband) alams\u00fcsteemi pealkirjafailide optimeerimine, mis on v\u00f5imaldanud v\u00e4hendada ehitusaega veel 9% v\u00f5rreldes esimese versiooni patchide ajaga. Kerneli C-failide arv, mis h\u00f5lmavad linux\/sched.h pealkirjafaili, on v\u00e4henenud 68% -lt 36% -le v\u00f5rreldes patchide esimese versiooniga (99% -lt 36% -le v\u00f5rreldes algse kerneli jaoks).
