From cf73d9970ea4f8cace5d8f02d2565a2723003112 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Wed, 2 Jul 2025 21:31:54 +0100 Subject: [PATCH] io_uring: don't use int for ABI __kernel_rwf_t is defined as int, the actual size of which is implementation defined. It won't go well if some compiler / archs ever defines it as i64, so replace it with __u32, hoping that there is no one using i16 for it.
