Don't leave space on EOL.

Caller of exec must report log_error when rstatus is passed.
|

so it does not look like we are executing command in the middle of
critical_section in log trace.

Static analyzis noticed we do not really need them - so removing.

As sync_local_dev_names() cannot be called within activation context,
add new parametr which allows to select if the sync call is needed
before executing new command.
|

|
|

Introduce sync_local_dev_names and CLVMD_CMD_SYNC_NAMES to issue fs_unlock.

Before fork, ensure cookie is reset so it's not shared between processes.

Patch updates exec_cmd() and adds 3rd parameter with pointer for
status value, so caller might examine returned status code.
If the passed pointer is NULL, behavior is unmodified.
Patch allows to confinue with lvresize if the failure from fsadm check is
caused by mounted filesystem as many of filesystem resize tools do support
online filesystem resize. (originally user had to use flag '-n' to bypass
this filesystem check)

_exit doesn't. If there were some open files, an error in exec and subsequent
exit() would cause the buffers to be flushed twice.
Example:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>
int main()
{
printf("buu");
if (!fork()) {
execl("/bin/true-not-exists", "/bin/true", NULL);
exit(1);
}
wait(NULL);
return 0;
}

Using argv[] list in exec_cmd() to allow more params for external commands.
Fsadm does not allow checking mounted filesystem.
Fsadm no longer accepts 'any other key' as 'no' answer to y/n.
Fsadm improved handling of command line options.
