Description

#if (LINUX_VERSION_CODE >= KERNEL_VERSION(5,0,0))
#define VERIFY_READ 0
#define VERIFY_WRITE 1
#define lttng_access_ok(type, addr, size) access_ok(addr, size)
#else /* LINUX_VERSION_CODE >= KERNEL_VERSION(5,0,0) /
#define lttng_access_ok(type, addr, size) access_ok(type, addr, size)
#endif / LINUX_VERSION_CODE >= KERNEL_VERSION(5,0,0) */

Should the first condition statement be "less than"?
On kernel 4.18, access_ok only takes two parameters but the second lttng_access_ok definition is invoked.
