you could fix it by change the data_len to _data_len. pls refer to the "struct request" in the 2.6.32 kernel header.

bugzilla.kernel.org is for actual bugs within the linux kernel, not for
problems with out of tree drivers.  The issue you're trying to report
needs to be fixed by LSI.  While it's not impossible they would notice
this request on the scsi mailing list, you're much more likely to get
their attention by requesting support directly from them.

@dujun - Thanks

It's actually a double underscore: __data_len
