2010/7/26 Penttilä Mika <mika.penttila@xxxxxxxxxx>: > I don't think this works because if the memmap pages get reused, the corresponding struct page->private could be used by chance in such a way that it has the value of MEMMAP_HOLE. Of course unlikely but possible. And after all the whole point of freeing part of the memmap is that it could be reused. > You're absolutely right. Previous version, I didn't do such as. In this version, I wanted to remove dependency of page->private and mem_section to identify hole memmap for using it in FLATMEM of ARM but make mistake. I will resend the patch Thanks for careful review. > --Mika > > > > -- Kind regards, Minchan Kim -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
