Subject: quota locking question
Date: Mon, 14 Dec 2009 17:30:49 +0300 [thread overview]
Message-ID: <87d42h1vc6.fsf@openvz.org> (raw)
According to dquot.c locking rules: dq_data_lock guards consistency
of dquot->dq_dqb with inode->i_blocks, i_bytes.
It is no clear to me what is the reason. Why do we need it ?
What use-case causes this requirement?
