As part of the THP work, I audited the callers of find_get_entry() and found one bug and three opportunities for optimisation. Patch 2 is the bugfix as it depends on using the same code as mincore_page(). I don't really like having find_get_swap_page() in mincore.c, but I can't find anywhere better to put it. Matthew Wilcox (Oracle) (4): mm: Factor find_get_swap_page out of mincore_page mm: Use find_get_swap_page in memcontrol mm: Optimise madvise WILLNEED proc: Optimise smaps for shmem entries fs/proc/task_mmu.c | 8 +----- include/linux/pagemap.h | 1 + mm/madvise.c | 20 +++++++------- mm/memcontrol.c | 25 ++--------------- mm/mincore.c | 59 +++++++++++++++++++++++------------------ 5 files changed, 47 insertions(+), 66 deletions(-) -- 2.27.0
