Hi Minchan (& all), Minchan Kim wrote: > [...] found __lru_cache_add has a bug. [...] [-] if (!pagevec_space(pvec) || PageCompound(page)) [+] if (!pagevec_add(pvec, page) || PageCompound(page)) Confirm that did plug the leak, thanks! Also I just saw this was known already: https://marc.info/?l=linux-kernel&m=146858368215856 Sorry for not noticing earlier, I did search for "4.1.28 memory leak", but not for "memleak". Many thanks, Jens
