4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Randy Dunlap <[email protected]> [ Upstream commit 1f3c790bd5989fcfec9e53ad8fa09f5b740c958f ] line-range is supposed to treat "1-" as "1-endoffile", so handle the special case by setting last_lineno to UINT_MAX.
