This patchset is supposed to replace Martin's
multipathd: add "force_reconfigure" option
patch from his uxlsnr overhaul patchset. It also makes the default
reconfigure be a weak reconfigure, but instead of adding a configuration
option to control this, it adds a new multipathd command,
"reconfigure all", to do a full reconfigure. The HUP signal is left
doing only weak reconfigures.
In order to keep from having two states that are handled nearly
identically, the code adds an extra variable to track the type of
configuration that was selected, but this could easily be switch to
use a new DAEMON_CONFIGURE_ALL state instead.
The final patch, that added the new command, is meant to apply on top of
Martin's changed client handler code. I can send one that works with the
current client handler code, if people would rather review that.
This change is going to affect some places, raw search:
$ git grep reconfigure
libdmmp/libdmmp.c: snprintf(cmd, _IPC_MAX_CMD_LEN, "%s", "reconfigure");
libmultipath/configure.c: * If we are in this code path (startup or forced reconfigure),
libmultipath/foreign.h: * don't support it. "multipathd reconfigure" starts foreign device
libmultipath/foreign.h: * This is called if multipathd reconfigures itself.
multipath/main.c: p += snprintf(p, n, "reconfigure");
multipathd/cli.c: r += add_key(keys, "reconfigure", RECONFIGURE, 0);
multipathd/cli_handlers.c:cli_reconfigure(void * v, char ** reply, int * len, void * data)
multipathd/cli_handlers.c: condlog(2, "reconfigure (operator)");
multipathd/cli_handlers.h:int cli_reconfigure(void * v, char ** reply, int * len, void * data);
multipathd/main.c: condlog(2, "reconfigure (delayed)");
multipathd/main.c: set_unlocked_handler_callback(RECONFIGURE, cli_reconfigure);
multipathd/main.c: condlog(2, "reconfigure (delayed)");

multipathd/main.c: condlog(2, "reconfigure (signal)");
multipathd/main.c: reconfigure(vecs);
multipathd/main.h:int reconfigure (struct vectors *);
multipathd/multipathd.8:happens, it will reconfigure the multipath map the path belongs to, so that this
multipathd/multipathd.8:.B reconfigure
multipathd/multipathd.service:ExecReload=/sbin/multipathd reconfigure
multipathd/uxlsnr.c: * do it once per reconfigure */
