This patchset clean-up and optimize highmem related code. [1] is just clean-up and doesn't introduce any functional change. [2-3] are for clean-up and optimization. These eliminate an useless lock opearation and list management. [4-5] is for optimization related to flush_all_zero_pkmaps(). Joonsoo Kim (5): mm, highmem: use PKMAP_NR() to calculate an index of pkmap mm, highmem: remove useless pool_lock mm, highmem: remove page_address_pool list mm, highmem: makes flush_all_zero_pkmaps() return index of last flushed entry mm, highmem: get virtual address of the page using PKMAP_ADDR()This patchset looks awesome to me. If you have a plan to respin, please CCed Peter.Thanks for review. I will wait more review and respin, the day after tomorrow. Version 2 will include fix about your comment.
Could you pick up second version of this patchset? [3] is changed to leave one blank line. [4] is changed in order to further optimize according to Minchan's comment. It return first index of flushed entry, instead of last index. Others doesn't changed. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
