[PATCH 4/5] all: wrap getdents64 syscall
From: Yury Norov <hidden>

Subsystem:

Alexander Viro, Christian Brauner, Linus Torvalds
This system call may be handled by compat handler if __ARCH_WANT_COMPAT_SYS_GETDENTS64 is defined. So we should declare wrapper otherwise only. Signed-off-by: Yury Norov <redacted> --- fs/readdir.c | 6 ++++++ 1 file changed, 6 insertions(+)
