From: Leo Yan Date: Wed, 4 Nov 2020 09:42:28 +0000 (+0800) Subject: perf lock: Correct field name "flags" X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e24a87b54ef3e39261f1d859b7f78416349dfb14;p=linux.git perf lock: Correct field name "flags" The tracepoint "lock:lock_acquire" contains field "flags" but not "flag". Current code wrongly retrieves value from field "flag" and it always gets zero for the value, thus "perf lock" doesn't report the correct result. This patch replaces the field name "flag" with "flags", so can read out the correct flags for locking.
