[lustre-devel] [PATCH 18/42] lustre: llite: report client stats sumsq

[James Simmons <jsimmons@infradead.org>]

From: Wang Shilong <wshilong@ddn.com>

Commit 2eeb tries to account sumsq for every client operation, but
lprocfs_counter_init() did not init them properly, also add a test
case to verify new format of client stats.

Fixes: 2eeb6dba81bc ("lustre: obd: add new LPROCFS_TYPE_*")
WC-bug-id: https://jira.whamcloud.com/browse/LU-13733
Lustre-commit: 8a1334626ec2f ("LU-13733 llite: report client stats sumsq")
