[mandatory]

	In ->fallocate() you must check the mode option passed in.  If your

filesystem does not support hole punching (deallocating space in the middle of a

file) you must return -EOPNOTSUPP if FALLOC_FL_PUNCH_HOLE is set in mode.

Currently you can only have FALLOC_FL_PUNCH_HOLE with FALLOC_FL_KEEP_SIZE set,

so the i_size should not change when hole punching, even when puching the end of

a file off.
