- rename datablock_addr() to data_blkaddr().
- wrap data_blkaddr() with f2fs_data_blkaddr() to clean up
parameters.

There are three status for background gc: on, off and sync, it's
a little bit confused to use test_opt(BG_GC) and test_opt(FORCE_FG_GC)
combinations to indicate status of background gc.
So let's remove F2FS_MOUNT_BG_GC and F2FS_MOUNT_FORCE_FG_GC mount
options, and add F2FS_OPTION().bggc_mode with below three status
to clean up codes and enhance bggc mode's scalability.
enum {
BGGC_MODE_ON, /* background gc is on */
BGGC_MODE_OFF, /* background gc is off */
BGGC_MODE_SYNC, /*
* background gc is on, migrating blocks
* like foreground gc
*/
};

and add F2FS_OPTION.fs_mode with below two status to indicate filesystem
mode.
enum {

You mean getting rid of this change or we need to fill F2FS_MOUNT_* hole as below:
