Browse source 
Port back
0.4.12-dev-973-g d29e216f99
[NTOSKRNL] In MmCreateImageSection, properly check whether cache was initialized
This fixes a crash that occurs if nul is typed in cmd.exe (BSOD0x1E)
----------
Port back also some unrelated formatting-improvements within section.c, e.g.: return(xyz) -> return xyz
A *partial* port of
0.4.15-dev-1793-g b7eb0fddf3
