4.9-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jeff Layton <jlayton@xxxxxxxxxx> [ Upstream commit 24c149ad6914d349d8b64749f20f3f8ea5031fe0 ] sparse says: fs/ceph/ioctl.c:100:28: warning: cast to restricted __le64 preferred_osd is a __s64 so we don't need to do any conversion. Also, just remove the cast in ceph_ioctl_get_layout as it's not needed.
