[f2fs-dev] [PATCH] f2fs: check all ones or zeros bitmap with integer data type for better mount performance

2013-10-22 Thread Chao Yu
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. Signed-off-by: Tan Shu Signed-off-by: Yu Chao --- fs/f2fs/s
