I removed the small tweaks to read-ahead code because they raised questions and are actually required for this series. Everything else is the same. Andrew: please drop the version of this that is currently in your tree even if you don't take this. The changes to fuse/nfs/ceph are not appropriate and I wouldn't want them to land by mistake. Thanks, NeilBrown --- NeilBrown (11): DOC: convert 'subsection' to 'section' in gfp.h MM: document and polish read-ahead code. MM: improve cleanup when ->readpages doesn't process all pages. fuse: remove reliance on bdi congestion nfs: remove reliance on bdi congestion ceph: remove reliance on bdi congestion Remove inode_congested() Remove bdi_congested() and wb_congested() and related functions f2fs: replace congestion_wait() calls with io_schedule_timeout() block/bfq-iosched.c: use "false" rather than "BLK_RW_ASYNC" Remove congestion tracking framework.
