This patch looks big, but basically it just moves code blocks. No functional changes. Our current code layout looks like a sandwitch. For example, a) between read/write handlers, we have update_used_max() helper function: static int zram_decompress_page static int zram_bvec_read static inline void update_used_max static int zram_bvec_write static int zram_bvec_rw b) RW request handlers __zram_make_request/zram_bio_discard are divided by sysfs attr reset_store() function and corresponding zram_reset_device() handler: static void zram_bio_discard static void zram_reset_device static ssize_t disksize_store static ssize_t reset_store static void __zram_make_request c) we first a bunch of sysfs read/store functions. then a number of one-liners, then helper functions, RW functions, sysfs functions, helper functions again, and so on. Reorganize layout to be more logically grouped (a brief description, `cat zram_drv.c | grep static` gives a bigger picture): -- one-liners: zram_test_flag/etc. -- helpers: is_partial_io/update_position/etc -- sysfs attr show/store functions + ZRAM_ATTR_RO() generated stats show() functions exception: reset and disksize store functions are required to be after meta() functions. because we do device create/destroy actions in these sysfs handlers. -- "mm" functions: meta get/put, meta alloc/free, page free static inline bool zram_meta_get static inline void zram_meta_put static void zram_meta_free static struct zram_meta *zram_meta_alloc static void zram_free_page -- a block of I/O functions static int zram_decompress_page static int zram_bvec_read static int zram_bvec_write static void zram_bio_discard static int zram_bvec_rw static void __zram_make_request static void zram_make_request static void zram_slot_free_notify static int zram_rw_page -- device contol: add/remove/init/reset functions (+zram-control class will sit here) static int zram_reset_device static ssize_t reset_store static ssize_t disksize_store static int zram_add static void zram_remove static int __init zram_init static void __exit zram_exit Signed-off-by: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Acked-by: Minchan Kim <minchan@kernel.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |
