From: Hugh Dickins Date: Tue, 5 Feb 2008 06:28:50 +0000 (-0800) Subject: tmpfs: move swap swizzling into shmem X-Git-Tag: v2.6.25-rc1~966 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=73b1262fa43a778b1e154deea632cdef5009d6a1;p=pandora-kernel.git tmpfs: move swap swizzling into shmem move_to_swap_cache and move_from_swap_cache functions (which swizzle a page between tmpfs page cache and swap cache, to avoid page copying) are only used by shmem.c; and our subsequent fix for unionfs needs different treatments in the two instances of move_from_swap_cache. Move them from swap_state.c into their callsites shmem_writepage, shmem_unuse_inode and shmem_getpage, making add_to_swap_cache externally visible. shmem.c likes to say set_page_dirty where swap_state.c liked to say SetPageDirty: respect that diversity, which __set_page_dirty_no_writeback makes moot (and implies we should lose that "shift page from clean_pages to dirty_pages list" comment: it's on neither).
