truncate_partial_nodes puts pages incorrectly in two cases.note that the value

first case:err happened in the first 'for' loop

This patch changes the method of calculating the number of summary blocks in function npages_for_summary_flush.
npages_for_summary_flush uses (SUMMARY_SIZE + 1) as the size of a f2fs_summary while the actual size is just SUMMARY_SIZE.
As a result, occasio

Previously, check_block_count check valid_map with bit data type in common
scenario that sit has all ones or zeros bitmap, it makes low mount performance.
So let's check the special bitmap with integer data type instead of the bit one.

use find_next_{zero_}bit_le for better performan
If you want to remove unnecessary BUG_ONs, you can just turn off F2FS_CHECK_FS

This config will support an option to remove so many BUG_ONs that degrade
