# The "count < sizeof(struct os_area_db)" comparison is type promoted to # size_t so negative values of "count" are treated as very high values and # we accidentally return success instead of a negative error code. # # This doesn't really change runtime much but it fixes a static checker # warning. # # Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> # Acked-by: Geoff Levand <geoff@infradead.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> #
