Documentation/filesystems/vfs.txt for more details.

[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.
