What does inconsistent indenting mean? Is this complaining about the conditional logic or the w->noflush assignment?

This line does look whitespace damaged (and I prefer the style with the first two branches of the if statement on the same line (i.e. 'if (error || w->noflush ||'), but breaking up the third bit looks wrong to me. The purpose of the indentation of the third part of the if statement is to highlight the compound nature of it. I.e., explicitly starting on a newline with the same indentation level as the previous statements, followed by further indentation on the subsequent lines that are sub-components of that statement helps highlight the logic and make the code more readable at a glance. So IOW, I suspect this could look something like:
if (error || w->noflush || (!w->must_flush && (jiffies - j->last_flush_write) < msecs_to_jiffies(c->opts.journal_flush_delay) && test_bit(JOURNAL_MAY_SKIP_FLUSH, &j->flags))) { w->noflush = true; ... } else { ...
Hm?
