Subject: [PATCH liburing] arch/syscall: Use __NR_mmap2 existence for preprocessor condition
Date: Tue, 26 Jul 2022 11:18:51 +0000	[thread overview]
Message-ID: <[email protected]> (raw)

Now __NR_mmap2 is only used for i386. But it is also needed for other
archs like ARM and RISCV32. Decide to use it based on the __NR_mmap2
definition as it's not defined on other archs. Currently, this has no
effect because other archs use the generic mmap definition from libc.
