The API to log the suspend reason was introduced with commit 57caa2ad5c
("power: Adds functionality to log the last suspend abort reason.").
It is called from functions enabled with PM_SLEEP and from functions
enabled with SUSPEND, but only available if SUSPEND is enabled.
This can result in build failures such as the following if PM_SLEEP
is enabled, but SUSPEND is not.

The PSCI SMP implementation is built only when both CONFIG_SMP and
CONFIG_ARM_PSCI are set, so a configuration that has the latter

Commit 1eff8f99f9 ("PM / Suspend: Print wall time at suspend entry and

Since RTC_LIB is not mandatory for all architetures, this can result in
the following build error.
suspend.c:(.text+0x2f36c): undefined reference to `rtc_time64_to_tm'
rtc_time64_to_tm() is implemented in rtc-lib, so SUSPEND now needs to

fixed the build for PPPoPNS and PPPoLAC by re-introducing a field in

get it used, so it is quite likely that the code never worked. Fix it up for

When closing a listen socket, tcp_abort currently calls
tcp_done without clearing the request queue. If the socket has a
child socket that is established but not yet accepted, the child
socket is then left without a parent, causing a leak.
Fix this by setting the socket state to TCP_CLOSE and calling
inet_csk_listen_stop with the socket lock held, like tcp_close
does.
Tested using net_test. With this patch, calling SOCK_DESTROY on a
listen socket that has an established but not yet accepted child
socket results in the parent and the child being closed, such
that they no longer appear in sock_diag dumps.

This implements SOCK_DESTROY for TCP sockets. It causes all
blocking calls on the socket to fail fast with ECONNABORTED and
causes a protocol close of the socket. It informs the other end
of the connection by sending a RST, i.e., initiating a TCP ABORT
as per RFC 793. ECONNABORTED was chosen for consistency with
FreeBSD.

This passes the SOCK_DESTROY operation to the underlying protocol
diag handler, or returns -EOPNOTSUPP if that handler does not
define a destroy operation.
Most of this patch is just renaming functions. This is not
strictly necessary, but it would be fairly counterintuitive to
have the code to destroy inet sockets be in a function whose name
starts with inet_diag_get.
