Subject: Re: More filesystem need this fix (xfs: use MMAPLOCK around filemap_map_pages())
Date: Mon, 14 Sep 2020 14:29:14 +0200	[thread overview]
Message-ID: <CAHc6FU6jU3qJppLvs-FrKVt0SryWDs_q9bV_=Lr6rZTwMfv+Tg@mail.gmail.com> (raw)
In-Reply-To: <20200914113516.GE4863@quack2.suse.cz>

Could the xfs mmap lock documentation please be cleaned up? For
example, the xfs_ilock description says:

> * In addition to i_rwsem in the VFS inode, the xfs inode contains 2
> * multi-reader locks: i_mmap_lock and the i_lock.  This routine allows
> * various combinations of the locks to be obtained.

The field in struct xfs_inode is called i_mmaplock though, not
i_mmap_lock. In addition, struct inode has an i_mmap_rwsem field which
is also referred to as i_mmap_lock. If that isn't irritating enough.

Thanks,
Andreas
