Filipe Manana c2f822635d btrfs: respect the max size in the header when activating swap file ... If we extended the size of a swapfile after its header was created (by the mkswap utility) and then try to activate it, we will map the entire file when activating the swap file, instead of limiting to the max size defined in the swap file's header. Currently test case generic/643 from fstests fails because we do not respect that size limit defined in the swap file's header. So fix this by not mapping file ranges beyond the max size defined in the swap header. This is the same type of bug that iomap used to have, and was fixed in commit 36ca7943ac ("mm/swap: consider max pages in iomap_swapfile_add_extent").
