Re: [HPDD-discuss] lustre/lnet/lnet/lib-move.c: memcpy with (struct iovec*)->iov_base, which is __user

Didn't Al change these to kvec instead of iovec? You have to
look at
the callers to figure out if it's actually a user space pointer or a
kernel pointer.
A patch was sent by Al on Dec 2 to replace iovec with kvec, in a thread
titled "[PATCH] staging:lustre:lnet: Incorrect type in assignment". Greg
replied on Dec 10 in another thread (also fixing this same warning) titled
"[PATCH] staging: lustre: Fix the warning messages about casting without
__user macro" that Al's patch was in the staging tree for 3.19-rc1.
