[PATCH v4 3/5] arm64: indent ptdump by level, aligning attributes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Outputs each level of the page table with two additional spaces for
parsers, distinction, and readability while maintaining the alignment of
region size and attributes.
