| |
From: Heiko Carstens <heiko.carstens@de.ibm.com>
A call to access_ok is missing a compat_ptr conversion. Introduced with b83733639a494d5f42fa00a2506563fbd2d3015d "compat: factor out compat_rw_copy_check_uvector from compat_do_readv_writev"
fs/compat.c: In function 'compat_rw_copy_check_uvector': fs/compat.c:629: warning: passing argument 1 of '__access_ok' makes pointer from integer without a cast
Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Jeff Moyer <jmoyer@redhat.com> ---
Probably should go into stable like the original patch.
