The delalloc reserved space is calculated in terms of number of bytes used by an integral number of blocks. This is done by rounding down the value of 'pos' to the nearest multiple of sectorsize. The file offset value held by 'pos' variable may not be aligned to sectorsize and hence when passing it as an argument to btrfs_delalloc_release_space(), we may end up releasing larger delalloc space than we originally had reserved.
