btrfs: don't use token set/get accessors for btrfs_item members

Browse source

The token versions of set/get accessors will be removed, use the normal
helpers. The btrfs_item members use that interface the most but there
are no real benefits anymore.

This reduces stack consumption on x86_64 release config:

setup_items_for_insert                           -32 (144 -> 112)
__push_leaf_left                                 -32 (176 -> 144)
btrfs_extend_item                                -16 (104 -> 88)
copy_for_split                                   -32 (144 -> 112)
btrfs_del_items                                  -16 (144 -> 128)
btrfs_truncate_item                              -24 (152 -> 128)
__push_leaf_right                                -24 (168 -> 144)

and module size:
