Now swapfile in f2fs directly submit IO to blockdev according to
swapfile extents reported by f2fs when swapon, therefore there is
no need to check IS_SWAPFILE when exec filesystem operation.

2.25.1
If the swapfile isn't created by pin and fallocate, it cann't be
guaranteed section-aligned, so it may be selected by f2fs gc. When
gc_pin_file_threshold is reached, the address of swapfile may change,
but won't be synchroniz to swap_extent, so swap will write to wrong
address, which will cause data corruption.

We should show above message only after we fail in check condition:
if ((pblock - main_blkaddr) & (blocks_per_sec - 1) ||
nr_pblocks & (blocks_per_sec - 1)) {
f2fs_err(sbi, "Swapfile does not align to section");
goto err_out;
}
And please use f2fs_{err,warn,info..} macro rather than pr_{err,warn,info..}.
Could you please fix above related issues in check_swap_activate_fast() as well.
