Subject: [PATCH] btrfs: ordered-extent: fix comment for btrfs ordered extent flag bits
Date: Thu, 11 Feb 2021 16:14:05 +0800 [thread overview]
Message-ID: <20210211081405.392006-1-wqu@suse.com> (raw)
There is small error in comment about BTRFS_ORDERED_* flags.
The 4 types are for ordered extent itself, not for direct io.
Only 3 types support direct io, REGULAR/NOCOW/PREALLOC.
Fix the comment to reflect that.
