fs: reduce the use of module.h wherever possible For files only using THIS_MODULE and/or EXPORT_SYMBOL, map them onto including export.h -- or if the file isn't even using those, then just delete the include. Fix up any implicit include dependencies that were being masked by module.h along the way. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>

[PATCH] fsstack: Introduce fsstack_copy_{attr,inode}_* Introduce several fsstack_copy_* functions which allow stackable filesystems (such as eCryptfs and Unionfs) to easily copy over (currently only) inode attributes. This prevents code duplication and allows for code reuse. [akpm@osdl.org: Remove unneeded wrapper] [bunk@stusta.de: fs/stack.c should #include <linux/fs_stack.h>] Signed-off-by: Josef "Jeff" Sipek <jsipek@cs.sunysb.edu> Cc: Michael Halcrow <mhalcrow@us.ibm.com> Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

VFS/fsstack: handle 32-bit smp + preempt + large files in fsstack_copy_inode_size Copy the inode size and blocks from one inode to another correctly on 32-bit systems with CONFIG_SMP, CONFIG_PREEMPT, or CONFIG_LBDAF. Use proper inode spinlocks only when i_size/i_blocks cannot fit in one 32-bit word.

mm: a few small updates for radix-swap Remove PageSwapBacked (!page_is_file_cache) cases from add_to_page_cache_locked() and add_to_page_cache_lru(): those pages now go through shmem_add_to_page_cache(). Remove a comment on maximum tmpfs size from fsstack_copy_inode_size(), and add a comment on swap entries to invalidate_mapping_pages(). And mincore_page() uses find_get_page() on what might be shmem or a tmpfs file: allow for a radix_tree_exceptional_entry(), and proceed to find_get_page() on swapper_space if so (oh, swapper_space needs #ifdef).

fsstack/ecryptfs: remove unused get_nlinks param to fsstack_copy_attr_all This get_nlinks parameter was never used by the only mainline user, ecryptfs; and it has never been used by unionfs or wrapfs either.
