Hold on, __packed should only be used as the absolute last possible
option to fix structure layout problems.
Also, a sub-structure of smc_cdc_msg, union smc_cdc_cursor, is still
marked with __aligned(8). That makes no sense at all.
Please fix this without using __packed, as __packed has a severe
detrimental effect on code generation for accessing such structure
on several cpu architectures.
Also, if this these are legitimate bug fixes you should target those
at 'net' not 'net-next'.
Thank you.
