w/ 4k-sized block config, I suffered performance regression issue while testing
fallocate() on pinfile.
Seems we need to add below code:
if (SUMS_PER_BLOCK == 1)
return f2fs_update_meta_page(sbi, (void *)sum_blk,
GET_SUM_BLOCK(sbi, segno));
Otherwise, we will load summary block whenever we change segment for curseg.
Thanks,
