MFSAL_truncate_check_perms : Checks authorization to perform an asynchronous truncate.

Checks authorization to perform an asynchronous truncate.

Parameters:

filehandle	[IN] mfsl object to be operated on.
pspecdata	[INOUT] mfsl object associated specific data
p_context	[IN] associated fsal context
p_mfsl_context	[INOUT] associated mfsl context
attrib_set	[IN] attributes to be set

Returns:

always FSAL_NO_ERROR (not yet implemented

MFSL_truncate : posts an asynchronous truncate and sets the cached attributes in return.

Posts an asynchronous truncate and sets the cached attributes in return. If the object is not asynchronous, then the content of object attributes will be used to populate it.

Parameters:

filehandle	[IN] mfsl object to be operated on.
p_context	[IN] associated fsal context
p_mfsl_context	[INOUT] associated mfsl context
size	[IN] new size
file_descriptor	[UNUSED] should be removed as stateful FSAL_truncate is removed from FSAL_PROXY
object_attributes	[INOUT] resulting attributes

Returns:

the same as FSAL_truncate

Todo:

: there may be a coefficient to be applied here
