Hi,
The previous version of my patch had a bug. Apparently function
gfs2_check_blk_type does need to check the non-clone bitmap. The other
two callers need to check the clone bitmap, if available.
So this version adds a parameter to specify. Also, I got rid of
function gfs2_get_block_type() in fav
Pass the offset of the write to gfs2_write_calc_reserv so that we can
then compute a better upper bound of the number of indirect blocks
required.

For normal writes, replace the existing version of
gfs2_write_calc_reserv with one that takes the offset of the write into
account. This allows to determine a lower bound for the maximum number
of indirect blocks required.
For __gfs2_fallocate, since gfs2_write_calc_reserv and calc_max_reserv
