Re: [lustre-devel] [PATCH] staging: lustre: Fix a spatch warning due to an assignment from kernel to user space

[Quentin Lambert]

Hi all,

I am looking at the drivers/staging/lustre/lustre/llite/dir.c:

1469                 /* Call mdc_iocontrol */
1470                 rc = obd_iocontrol(LL_IOC_FID2MDTIDX, exp, 
sizeof(fid), &fid,
1471                                    &index);
1472                 if (rc)

and sparse says:

drivers/staging/lustre/lustre/llite/dir.c:1471:37: warning: incorrect 
type in argument 5 (different address spaces)

I was wondering if there was any value to add a cast to fix the warning?
And I guess this solution would also apply in my original patch to

drivers/staging/lustre/lnet/lnet/lib-socket.c
