From: Raghavendra D Prabhu <rprabhu@xxxxxxxxxxx> Following are some of the fixes / improvements to the page cache readahead: first four are minor fixes along the readahead path, the last one is an improvement to use find_get_pages in __do_page_cache_readahead. Raghavendra D Prabhu (5): mm/readahead: Check return value of read_pages mm/readahead: Change the condition for SetPageReadahead Remove file_ra_state from arguments of count_history_pages. Move the check for ra_pages after VM_SequentialReadHint() mm/readahead: Use find_get_pages instead of radix_tree_lookup. mm/filemap.c | 5 +++-- mm/readahead.c | 50 ++++++++++++++++++++++++++++++++++---------------- 2 files changed, 37 insertions(+), 18 deletions(-) -- 1.7.12.1 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
