[PATCH 2/3] btrfs: remove dead comment on btrfs_add_dead_root()
From: Qu Wenruo <hidden>
Date: 2021-06-28 10:16:50
Subsystem:
btrfs file system, filesystems (vfs and infrastructure), the rest · Maintainers:
Chris Mason, David Sterba, Alexander Viro, Christian Brauner, Linus Torvalds
The old comment is from the initial merge of btrfs, but since commit
5d4f98a28c7d ("Btrfs: Mixed back reference (FORWARD ROLLING FORMAT
CHANGE)") changed the behavior to not to allocate any extra memory,
the comment on the memory allocation part is out-of-date.
Fix it by removing the dead part and change it to modern behavior.
