commit 50ab8ec74a153eb30db26529088bc57dd700b24c upstream.
See http: //www.infradead.org/rpr.html X-Evolution-Source: 1451162204.2173.11@leira.trondhjem.org Content-Transfer-Encoding: 8bit Mime-Version: 1.0
We support OFFSET_MAX just fine, so don't round down below it. Also switch to using min_t to make the helper more readable.
