[PATCH 1/5] arm64: rename defer_reserve_crashkernel() to have_zone_dma()

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

 



From: Mike Rapoport <rppt@xxxxxxxxxxxxx>

The new name better describes what the function does and does not
restrict its use to crash kernel reservations.
