From: Muhammad Usama Anjum <usama.anjum@xxxxxxxxxxxxx> commit f30beffd977e98c33550bbeb6f278d157ff54844 upstream. grep -rnIF "#define __NR_userfaultfd" tools/include/uapi/asm-generic/unistd.h:681:#define __NR_userfaultfd 282 arch/x86/include/generated/uapi/asm/unistd_32.h:374:#define __NR_userfaultfd 374 arch/x86/include/generated/uapi/asm/unistd_64.h:327:#define __NR_userfaultfd 323 arch/x86/include/generated/uapi/asm/unistd_x32.h:282:#define __NR_userfaultfd (__X32_SYSCALL_BIT + 323) arch/arm/include/generated/uapi/asm/unistd-eabi.h:347:#define __NR_userfaultfd (__NR_SYSCALL_BASE + 388) arch/arm/include/generated/uapi/asm/unistd-oabi.h:359:#define __NR_userfaultfd (__NR_SYSCALL_BASE + 388) include/uapi/asm-generic/unistd.h:681:#define __NR_userfaultfd 282 The number is dependent on the architecture. The above data shows that: x86 374 x86_64 323 The value of __NR_userfaultfd was changed to 282 when asm-generic/unistd.h was included. It makes the test to fail every time as the correct number of this syscall on x86_64 is 323. Fix the header to asm/unistd.h.
