The following missing prototypes will be fixed:
1) btrfs.c::handle_special_globals()
2) check/mode-lowmem.c::repair_ternary_lowmem()
3) extent-tree.c::btrfs_search_overlap_extent()
Above 3 can be fixed by making them static
4) utils.c::btrfs_check_nodesize()
Fixed by moving it to fsfeatures.c
5) chunk-recover.c::btrfs_recover_chunk_tree()
6) super-recover.c::btrfs_recover_superblocks()
Fixed by moving the declaration from cmds-rescue.c to rescue.h
7) utils-lib.c::arg_strtou64()
8) utils-lib.c::lookup_path_rootid()
Fixed by include "utils.h"
9) free-space-tree.c::set_free_space_tree_thresholds()
Fixed by deleting it, as there is no user.
10) free-space-tree.c::convert_free_space_to_bitmaps()
11) free-space-tree.c::convert_free_space_to_extents()
12) free-space-tree.c::__remove_from_free_space_tree()
13) free-space-tree.c::__add_to_free_space_tree()
14) free-space-tree.c::btrfs_create_tree()
Fixed by making them static.
