Hi, > From: David Howells, Sent: Friday, August 30, 2019 10:58 PM <snip> > --- > > Documentation/watch_queue.rst | 22 ++++++- > arch/alpha/kernel/syscalls/syscall.tbl | 1 > arch/arm/tools/syscall.tbl | 1 > arch/ia64/kernel/syscalls/syscall.tbl | 1 It seems to lack modification for arch/arm64. I'm not sure whether this is related, but my environment (R-Car H3 / r8a7795) cannot boot on next-20190902 which contains this patch. I found an issue on the patch 08/11, so I'll report on the email thread later. > arch/m68k/kernel/syscalls/syscall.tbl | 1 > arch/microblaze/kernel/syscalls/syscall.tbl | 1 > arch/mips/kernel/syscalls/syscall_n32.tbl | 1 > arch/mips/kernel/syscalls/syscall_n64.tbl | 1 > arch/mips/kernel/syscalls/syscall_o32.tbl | 1 > arch/parisc/kernel/syscalls/syscall.tbl | 1 > arch/powerpc/kernel/syscalls/syscall.tbl | 1 > arch/s390/kernel/syscalls/syscall.tbl | 1 > arch/sh/kernel/syscalls/syscall.tbl | 1 > arch/sparc/kernel/syscalls/syscall.tbl | 1 > arch/x86/entry/syscalls/syscall_32.tbl | 1 > arch/x86/entry/syscalls/syscall_64.tbl | 1 > arch/xtensa/kernel/syscalls/syscall.tbl | 1 > drivers/base/Kconfig | 9 +++ > drivers/base/Makefile | 1 > drivers/base/watch.c | 90 +++++++++++++++++++++++++++ > include/linux/device.h | 7 ++ > include/linux/syscalls.h | 1 > include/uapi/asm-generic/unistd.h | 4 + > kernel/sys_ni.c | 1 > 24 files changed, 149 insertions(+), 2 deletions(-) > create mode 100644 drivers/base/watch.c Best regards, Yoshihiro Shimoda
