As written I think the patch behaves like this:
if (zero_state == 0) /* We've not hit the upper limit */
if (zeroed pages >= high count) /* hit the upper limit */
zero_state = 1;
return STOP_ZEROING_PAGES;
return KEEP_ZEROING_PAGES;
if (zero_state == 1) /* We've hit the upper limit before */
if (zeroed_pages >= LOW MARK) /* Still have free pages; also covers high */
return STOP_ZEROING_PAGES;
/* We've seen an upper limit; now we're below the lower limit. */
/* Restore to 0 (not seen high limit) */
zero_state = 0;
return KEEP_ZEROING_PAGES;
What was wrong with this?
