This patch addresses the following build warnings:
fsx.c: In function 'do_punch_hole':
fsx.c:940:3: warning: this 'if' clause does not guard... [-Wmisleading-indentation]
if (!quiet && testcalls > simulatedopcount)
^~
fsx.c:942:4: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'if'
log4(OP_PUNCH_HOLE, offset, length, FL_SKIPPED);

growfiles.c: In function 'notify_others':
growfiles.c:1458:6: warning: this 'if' clause does not guard... [-Wmisleading-indentation]
if ( Forker_pids[ind] != Pid )
^~
growfiles.c:1462:10: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'if'
kill(Forker_pids[ind], SIGUSR2);
^~~~
The warnings in fsx.c were just spacing issues of the form:
if (length == 0) {
if (!quiet && testcalls > simulatedopcount)
prt("skipping zero length punch hole\n");
log4(OP_PUNCH_HOLE, offset, length, FL_SKIPPED);
return;
}
Where the log4() call just needs to be unindented. log4() calls elsewhere
in that same file are not protected with any sort of 'quiet' check, and
commonly follow prt() calls which are. See doread(), domapread(), etc.
The warning from growfiles.c was actually a bug. notify_others() is
looping through the Forker_pids[] array and sending SIGUSR2 to all other
processes. However, with the current logic it only *logs* the kill for
other processes, and kills all other processes plus the Forker_pids[] entry
that matches 'Pid'.
