Subject: [PATCH v4 33/68] btrfs: extent-io: make type of extent_state::state to be at least 32 bits
Date: Wed, 21 Oct 2020 14:25:19 +0800 [thread overview]
Message-ID: <20201021062554.68132-34-wqu@suse.com> (raw)
In-Reply-To: <20201021062554.68132-1-wqu@suse.com>
Currently we use 'unsigned' for extent_state::state, which is only ensured
to be at least 16 bits.
But for incoming subpage support, we are going to introduce more bits to
at least match the following page bits:
- PageUptodate
- PagePrivate2
Thus we will go beyond 16 bits.
To support this, make extent_state::state at least 32bit and to be more
explicit, we use "u32" to be clear about the max supported bits.
This doesn't increase the memory usage for x86_64, but may affect other
architectures.
