Dave Chinner bf59170a66 xfs: obey minleft values during extent allocation correctly ... When allocating an extent that is long enough to consume the remaining free space in an AG, we need to ensure that the allocation leaves enough space in the AG for any subsequent bmap btree blocks that are needed to track the new extent. These have to be allocated in the same AG as we only reserve enough blocks in an allocation transaction for modification of the freespace trees in a single AG. xfs_alloc_fix_minleft() has been considering blocks on the AGFL as free blocks available for extent and bmbt block allocation, which is not correct - blocks on the AGFL are there exclusively for the use of the free space btrees. As a result, when minleft is less than the number of blocks on the AGFL, xfs_alloc_fix_minleft() does not trim the given extent to leave minleft blocks available for bmbt allocation, and hence we can fail allocation during bmbt record insertion.
