The following changes are made: (1) Make the file descriptors returned by open_tree(), fsopen(), fspick() and fsmount() O_CLOEXEC by default and remove the flags that allow this to be specified from the UAPI, shuffling other flags down as appropriate. fcntl() can still be used to change the flag. (2) Make the name of the anon inode object "[fscontext]" with square brackets to match other users. (3) Fix the numbering of the mount API syscalls to be in the common space rather than in the arch-specific space. (4) Wire up the mount API syscalls on all arches (it's only on x86 currently). Thanks, David --- Christian Brauner (2): uapi, fs: make all new mount api fds cloexec by default uapi, fsopen: use square brackets around "fscontext" David Howells (2): uapi, x86: Fix the syscall numbering of the mount API syscalls uapi: Wire up the mount API syscalls on non-x86 arches arch/alpha/kernel/syscalls/syscall.tbl | 6 ++++++ arch/arm/tools/syscall.tbl | 6 ++++++ arch/arm64/include/asm/unistd.h | 2 +- arch/arm64/include/asm/unistd32.h | 12 ++++++++++++ arch/ia64/kernel/syscalls/syscall.tbl | 6 ++++++ arch/m68k/kernel/syscalls/syscall.tbl | 6 ++++++ arch/microblaze/kernel/syscalls/syscall.tbl | 6 ++++++ arch/mips/kernel/syscalls/syscall_n32.tbl | 6 ++++++ arch/mips/kernel/syscalls/syscall_n64.tbl | 6 ++++++ arch/mips/kernel/syscalls/syscall_o32.tbl | 6 ++++++ arch/parisc/kernel/syscalls/syscall.tbl | 6 ++++++ arch/powerpc/kernel/syscalls/syscall.tbl | 6 ++++++ arch/s390/kernel/syscalls/syscall.tbl | 6 ++++++ arch/sh/kernel/syscalls/syscall.tbl | 6 ++++++ arch/sparc/kernel/syscalls/syscall.tbl | 6 ++++++ arch/x86/entry/syscalls/syscall_32.tbl | 12 ++++++------ arch/x86/entry/syscalls/syscall_64.tbl | 12 ++++++------ arch/xtensa/kernel/syscalls/syscall.tbl | 6 ++++++ fs/fsopen.c | 15 +++++++-------- fs/namespace.c | 11 ++++------- include/uapi/asm-generic/unistd.h | 14 +++++++++++++- include/uapi/linux/mount.h | 18 +++--------------- 22 files changed, 136 insertions(+), 44 deletions(-)
