Subject: [PATCH AUTOSEL for 4.9 11/33] dynamic-debug-howto: fix optional/omitted ending line number to be LARGE instead of 0
Date: Sat, 2 Dec 2017 15:52:18 +0000 [thread overview]
Message-ID: <20171202155204.7691-11-alexander.levin@verizon.com> (raw)
In-Reply-To: <20171202155204.7691-1-alexander.levin@verizon.com>
From: Randy Dunlap <rdunlap@infradead.org>
[ 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.
Fixes this error:
dynamic_debug:ddebug_parse_query: last-line:0 < 1st-line:1
dynamic_debug:ddebug_exec_query: query parse failed
