Nothing exciting, mostly cleanup, preparation for what will probably be two more patchsets coming over the next few weeks, first simplifying tmpfs by getting rid of its ->readpage (give it a splice instead), then getting rid of its peculiar swap index (use radix_tree instead). The ordering here is somewhat illogical, arranged in the hope that at least the first four can get into 30-rc, which would simplify the dependencies between linux-next and mmotm. Changes since last week's v1: - removed the original 1/14, which was adding cleancache_flush_inode() into invalidate_mapping_pages(): I stand by that patch, but feedback from Dan Magenheimer and Chris Mason implies that cleancache has a bigger problem in this area (flushing too much or too little, unable to distinguish truncate from evict, potential issue with O_DIRECT) which we shall discuss and deal with separately. - incorporated feedback from Christoph Hellwig, mainly electing for an explicit call to shmem_truncate_range() from drm/i915, which will also help if we replace ->truncate_range by ->fallocate later; so a new 2/14 which moves shmem function prototypes into shmem_fs.h. 1,2,3,4 affect the interface between tmpfs and drm very slightly. Once they're in 30-rc, drm maintainers could take 5,6,7,8 out of mmotm and into linux-next (or even 30-rc). 1/14 mm: move vmtruncate_range to truncate.c 2/14 mm: move shmem prototypes to shmem_fs.h 3/14 tmpfs: take control of its truncate_range 4/14 tmpfs: add shmem_read_mapping_page_gfp 5/14 drm/ttm: use shmem_read_mapping_page 6/14 drm/i915: use shmem_read_mapping_page 7/14 drm/i915: use shmem_truncate_range 8/14 drm/i915: more struct_mutex locking 9/14 mm: cleanup descriptions of filler arg 10/14 mm: truncate functions are in truncate.c 11/14 mm: tidy vmtruncate_range and related functions 12/14 mm: consistent truncate and invalidate loops 13/14 mm: pincer in truncate_inode_pages_range 14/14 tmpfs: no need to use i_lock drivers/gpu/drm/drm_gem.c | 1 drivers/gpu/drm/i915/i915_dma.c | 3 drivers/gpu/drm/i915/i915_gem.c | 38 ++--- drivers/gpu/drm/i915/intel_overlay.c | 5 drivers/gpu/drm/ttm/ttm_tt.c | 5 include/linux/mm.h | 3 include/linux/pagemap.h | 12 - include/linux/shmem_fs.h | 21 +++ include/linux/swap.h | 10 - mm/filemap.c | 14 +- mm/memcontrol.c | 1 mm/memory.c | 24 --- mm/shmem.c | 88 +++++++++---- mm/swapfile.c | 2 mm/truncate.c | 159 +++++++++++++------------ 15 files changed, 206 insertions(+), 180 deletions(-) Hugh -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
