Description

The MDT getattr statistic in procfs is not incremented when clients perform stat operations on files. For example,

$ echo clear | sudo tee /proc/fs/lustre/mdt/lustre-MDT0000/md_stats
clear
$ grep getattr /proc/fs/lustre/mdt/lustre-MDT0000/md_stats
$ sudo touch /mnt/lustre/test
$ ls -l /mnt/lustre/test
rw-rr- 1 root root 0 Apr 12 17:42 /mnt/lustre/test
$ grep getattr /proc/fs/lustre/mdt/lustre-MDT0000/md_stats
$

Should getattr get incremented in this case?
