Subject: [net-next,v1] net: e1000e: solve insmod 'Unknown symbol mutex_lock' error
Date: Fri, 17 Sep 2021 14:16:54 +0000 [thread overview]
Message-ID: <20210917141654.8978-1-chenhaoa@uniontech.com> (raw)
After I turn on the CONFIG_LOCK_STAT=y, insmod e1000e.ko will report:
[ 5.641579] e1000e: Unknown symbol mutex_lock (err -2)
[ 90.775705] e1000e: Unknown symbol mutex_lock (err -2)
[ 132.252339] e1000e: Unknown symbol mutex_lock (err -2)
This problem fixed after include <linux/mutex.h>.
