ext2: don't set *count in the case of failure in ext2_try_to_allocate()

2019-10-31T14:40:44+00:00

Currently we set *count to num(value 0) in the failure
of block allocation in ext2_try_to_allocate(). Without
reservation, we reuse *count(value 0) to retry block
allocation and wrong *count will cause only allocating
maximum 1 block even though having sufficent free blocks
in that block group. Finally, it probably cause significant
fragmentation.

ext2: fix block range in ext2_data_block_valid()

2019-07-31T10:04:42+00:00

For block validity we should check the block range
from start_block to start_block + count - 1, so fix
the range in ext2_data_block_valid() and also modify
the count argument properly in calling place.
