[Linux-kernel-mentees] [PATCH] ptrace: Prevent kernel-infoleak in ptrace_get_syscall_info()

ptrace_get_syscall_info() is copying uninitialized stack memory to userspace due to the compiler not initializing holes in statically allocated structures. Fix it by initializing `info` with memset(). Cc: sta...@vger.kernel.org Fixes: 201766a20e30 ("ptrace: add PTRACE_GET_SYSCALL_INFO request")
