Subject: [PATCH v7 15/22] parisc: define syscall_get_error()
Date: Mon, 7 Jan 2019 05:54:14 +0300 [thread overview]
Message-ID: <20190107025414.GO1207@altlinux.org> (raw)
In-Reply-To: 20190107025101.GA1182@altlinux.org
syscall_get_error() is required to be implemented on all
architectures in addition to already implemented syscall_get_nr(),
syscall_get_arguments(), syscall_get_return_value(), and
syscall_get_arch() functions in order to extend the generic
ptrace API with PTRACE_GET_SYSCALL_INFO request.
