From 060ff688cadac398a17f09bd87b16fd0bf943899 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Wed, 20 Apr 2016 20:49:14 -0400 Subject: lustre: don't need to lock inode in directory lseek Note that lustre has its private mutex protecting directory pagecache; if they ever remove it, they'll need to be careful with PageChecked() use.
