[LU-8801] ldiskfs quota accounting iterator is flawed

Related — Thu, 2 Feb 2017 17:14:45 +0000

The ldiskfs quota accounting iterator is flawed, that'll result in some accounting entries being missed in the output of proc files (acct_user & acct_group).

This can be reproduced by:

Create a fresh filesystem;

Run the following script to generate large amount of accounting entries:

#!/bin/bash
for i in `seq 10000`; do
        touch /mnt/lustre/file_$i
        chown $i:$i /mnt/lustre/file_$i
done

Verify proc file by: cat /proc/fs/lustre/osd-ldiskfs/lustre-MDT0000/quota_slave/acct_user; Some entries are missed in the output.
