History
Brian Behlendorf c495fe2c1c Limit max_hw_sectors_kb to 16M 
When support for large blocks was added DMU_MAX_ACCESS was increased
to allow for blocks of up to 16M to fit in a transaction handle.
This had the side effect of increasing the max_hw_sectors_kb for
volumes, which are scaled off DMU_MAX_ACCESS, to 64M from 10M.

This is an issue for volumes which by default use an 8K block size
because it results in dmu_buf_hold_array_by_dnode() allocating a
64K array for the dbufs.  The solution is to restore the maximum
size to ~10M.  This patch specifically changes it to 16M which is
close enough.
